The prognosis following acute primary glenohumeral dislocation.

We have studied 105 patients with 107 acute, primary, dislocations of the glenohumeral joint seen between January 1, 1991 and July 1, 1994. The mean time of follow-up was 71 months (46 to 91). In 34% the injury occurred during a sports activity and in 28% at home. The bias toward sport was even greater in patients less than 40 years of age, and in men. In patients older than 40 years of age, and in women, the dislocation occurred more often at home. The overall probability of recurrence within four years was 26%. Age was the most significant prognostic factor in recurrence which took place in 64% of patients less than 20 years of age and in 6% of those older than 40 years. Statistically, there was no difference between the rates of recurrence in patients who were active in sport and those who were not. The mean Rowe score for the whole group was 87 (15 to 100). Associated fractures were found in 20 patients (19%) and nerve injuries in 22 (21%). None of those in whom a fracture of the greater tuberosity was seen subsequently suffered a recurrent dislocation. At follow-up we found that 36 patients (34%) had not returned to their former employment but in only 2% was this owing to the injured shoulder.

Biologic classification as an alternative to anatomic staging for clinically localized prostate cancer: a proposal based on patients treated with external beam radiotherapy.

OBJECTIVES: The prognostic significance of clinical stage in patients with prostate cancer who are treated with external beam radiotherapy is unclear. This study evaluates multiple pretreatment factors, including clinical stage, to determine which are the best prognostic factors, and develops a classification system based on these factors. METHODS: All 249 evaluable patients with clinically localized adenocarcinoma of the prostate treated with definitive conformal external beam radiotherapy without androgen deprivation at our institution between 1989 and 1993 were analyzed. Clinical stage, serum PSA level, Gleason score, race, and history of transurethral resection of the prostate (TURP) were evaluated for their ability to predict biochemical disease-free survival (BDFS). Factors predictive of BDFS were then used to construct a classification system. The classification system was then analyzed for its ability to predict BDFS, distant metastases, local recurrence, and clinical disease free survival in univariate and multivariate analyses. Median follow-up was 27 months. RESULTS: Gleason score and PSA predicted BDFS in multivariate analysis (both P <0.0001), whereas clinical stage, race, and history of a TURP did not. These two biologic factors were combined into a four-level classification system. This classification system was analyzed together with Gleason score and PSA and was found to be the only predictor of BDFS on multivariate analysis (P <0.0001). In addition, this classification system was the only predictor of distant metastases in multivariate analysis (P <0.0001). CONCLUSIONS: The classification system derived herein based on the biologic factors of Gleason score and serum PSA levels is the sole predictor of distant metastases and biochemical recurrence for patients treated with definitive conformal external beam radiotherapy for clinically localized prostate cancer. This classification system may be useful when comparing competing therapies and stratifying patients in clinical trials, but requires validation from other institutions and other therapies prior to its widespread use.

Cerebral perfusion pressure for prediction of recurrent intracranial hypertension after primary decompressive craniectomy.

BACKGROUND: Decompressive craniectomy (DC) with dural grafting may be performed in patients with moderate (Glasgow-Coma-Scale [GCS] score 9-12 points) or severe traumatic brain injury (TBI; GCS score <or= 8 points) and threatening herniation. However, its effectiveness especially after primary craniectomy is still discussed due to missing evidence of improved outcome. The objectives of this study were to show the incidence of recurrent intracranial hypertension after primary DC, to identify predictive parameters for secondary DC, and to evaluate the long-term neurological performance 12 months after TBI. METHODS: Between 01/1997 and 06/2001 all consecutive patients admitted with moderate or severe isolated TBI were enrolled in this study. They were treated according to the guidelines of the European Brain Injury Consortium, and the American Association of Neurosurgical Surgeons (AANS) for the management of severe TBI. Process and clinical data as well as every intervention were registered prospectively. The long-term neurological status was reassessed using the Glasgow Outcome Score (GOS) 12 months after TBI. Statistical comparison was performed using Mann-Whitney-U test, and multivariate testing by means of logistic regression analysis. RESULTS: Fifty-one (43 males, 8 females; median age 51.4 years) of 119 isolated TBI patients were included. Ten patients (8 males, 2 females; median age 38.4 years) underwent secondary extended or contralateral DC in their clinical course. Three of them (30%) died at a median of 1 day after revision respectively 6 days after TBI. According to univariate analysis, secondary DC significantly correlated with arterial hypotension (p = 0.020) and otorrhagia at admission (p = 0.041), skull base fracture (p = 0.011) and decreased maximum cerebral perfusion pressure (CPP; p = 0.006) after primary surgery. Multivariate analysis identified decreased maximum CPP as the only independent predictive parameter (p = 0.036) for secondary DC and unfavourable GOS after 12-months follow-up. CONCLUSION: Arterial hypotension, otorrhagia at admission and skull base fractures are negatively influencing the mortality and morbidity of patients with isolated moderate or severe TBI. However, only decreased maximum CPP may independently indicate secondary DC after primary craniectomy in case of recurrent intracranial hypertension.

Arthroscopic stabilization of the shoulder: a prospective randomized study of absorbable versus nonabsorbable suture anchors.

PURPOSE: The aim of this study was to evaluate, prospectively, outcomes following arthroscopic Bankart repair performed with 2 types of suture anchor--the G II (DePuy Mitek, Raynham, MA) nonabsorbable anchor and the Panalok (DePuy Mitek) absorbable anchor. METHODS: Patients with a diagnosis of recurrent traumatic anterior instability of the shoulder who were seen in a single unit between April of 2000 and June of 2003 were considered for inclusion in the study. Patients were assessed preoperatively and postoperatively by means of a subjective, patient-related outcome measurement tool (Oxford Instability Score), a visual analogue scale for pain and instability (VAS Pain and VAS Instability), and a quality-of-life questionnaire (Short Form-12 [SF-12]). Length of follow-up was 1.5 to 5 years (mean, 2.6 y). The incidence of recurrent instability and the level of sporting ability were recorded. Patients were randomized to undergo surgical repair with nonabsorbable or absorbable anchors. RESULTS: A total of 130 patients were included in this study, of whom 6 were lost to follow-up; therefore 124 patients (95%) completed the study. Both types of anchor were highly effective. No differences in rate of recurrence or in any of the scores were noted between the 2 groups. In all, 4 patients in the nonabsorbable group and 3 in the absorbable group experienced additional episodes of dislocation after a traumatic event. Rate of redislocation in the whole series was therefore 6%. In addition, 4 patients, all of them from the absorbable group (4%), described ongoing symptoms of instability but no true dislocations. In all, 85% of the patient group have returned to their previous level of sporting activity. CONCLUSIONS: No differences in outcomes of arthroscopic Bankart repair were seen whether absorbable or nonabsorbable anchors were used. Both are highly effective, with a redislocation rate of 6%. LEVEL OF EVIDENCE: Level I, therapeutic randomized controlled trial.

[Arthroscopic extra-articular Bankart procedure].

The arthroscopic extraarticular Bankart procedure tries to imitate the open Bankart procedure. An anterior-inferior transmuscular approach through the subscapular muscle permits to implant self-locking tacks into the anterior inferior third of the glenoid rim. The extraarticular location of the implants makes a superomedial capsular shift possible, if required. A total of 257 arthroscopic repairs following traumatic recurrent anterior shoulder dislocation have been carried out between 1992 and 1996. 177 patients were treated only with bioabsorbable Suretac device. Clinical and radiological follow up was possible in 165 patients. According to the Rowe score 69.7% were classified as excellent, 10.9% as good, 9.7% fair and 9.7% poor. Postoperative complications: the recurrence rate was 9.7%, allergic reactions representing a foreign body reaction to the synthetic material were seen in 5 cases (3%) and a frozen shoulder in 6 cases 3.6%). 61% of the patients involved in overhead or contact sports returned to their preoperative sport activities.

Five-year results of a phase II trial of hyperfractionated radiotherapy and concurrent daily cisplatin chemotherapy for stage III non-small-cell lung cancer.

The purpose of this study was to evaluate the 5-year results for a phase II trial of hyperfractionated radiotherapy (RT) and concurrent daily cisplatin chemotherapy. Between August 1994 and December 1999, 63 patients with stage IIIA and stage IIIB non-small-cell lung cancer were treated with RT to a dose of 69.6 Gy at 1.2 Gy twice daily with daily cisplatin at 6 mg/m. Thirty-seven patients elected to receive consolidation carboplatin and paclitaxel chemotherapy. Recurrence and survival outcomes were evaluated by Kaplan-Meier analysis. Acute and late side effects were scored by the Radiation Therapy Oncology Group (RTOG) grading system. Radiographic complete or partial tumor response was achieved in 34 of 63 (54%) of cases. Median absolute survival was 20.1 months. Median time to local recurrence and distant metastases were 10.6 and 8.6 months, respectively. Overall survival rates were 57%, 35%, and 23% at 1, 3, and 5 years, respectively. Survival was significantly greater for patients receiving consolidation chemotherapy (50% versus 20% at 3 years). Only 5 patients (7%) experienced Grade 3 or 4 esophagitis. There were 16 cases of Grade 1 or 2 pneumonitis; steroid therapy resolved symptoms in 9 patients. This regimen of hyperfractionated RT and chemotherapy achieved significant response, and 5-year survival rates with acceptable toxicity.

Recurrent subacute torsion: prospective study of effects on testicular morphology and function.

A prospective study was done on 43 consecutive patients with a diagnosis of recurrent subacute testicular torsion. All patients underwent full examination, hormonal assays and seminal fluid analysis before scrotal exploration, bilateral testicular biopsy and fixation. Seminal fluid analysis and hormonal assays were repeated 3 months postoperatively. Of the patients 36 were cured of recurrent pain, 35 of whom had a horizontally lying testis. No hormonal abnormalities were found preoperatively or postoperatively. Three patients had abnormal seminal fluid analysis. Testicular biopsies, including Johnsen scores, were abnormal in these 3 patients and normal in the other 33. It is concluded that patients with recurrent subacute torsion can be identified accurately and treated satisfactorily. There is little evidence that these patients suffer testicular damage as a result of this subacute torsion or that any pre-existing cellular abnormality exists to explain the oligospermia that frequently is seen in patients who have acute testicular torsion.

The decrease of erythrocyte catechol-O-methyltransferase activity in depressed patients and its diagnostic significance.

Erythrocyte catechol-O-methyltransferase (COMT) activity was measured in normal and depressed populations before specific medication. In the groups of patients, anxiety and depression scores were evaluated by the AMDP rating scale. The authors found lower enzyme activity in patients with major depression, recurrent and bipolar disorder, depressed, but no change was found in dysthymic disorder when compared to control values. However, there was no relationship between COMT activity and age, anxiety and depression scores of patients. Furthermore, the subdivision into two subpopulations, one with normal COMT activity and another with lower COMT activity, did not make it possible to assign a role to the enzyme in the severity of depression. The enzyme could, however, be considered as a genetic marker of depressive vulnerability.

Evidence-based estimates of outcome in patients irradiated for intraocular melanoma.

BACKGROUND: Melanoma of the eye is the only potentially fatal ocular malignancy in adults. Until radiation therapy gained wide acceptance in the 1980s, enucleation was the standard treatment for the tumor. Long-term results after proton beam irradiation are now available. METHODS: We developed risk score equations to estimate probabilities of the 4 principal treatment outcomes-local tumor recurrence, death from metastasis, retention of the treated eye, and vision loss-based on an analysis of 2069 patients treated with proton beam radiation for intraocular melanoma between July 10, 1975, and December 31, 1997. Median follow-up in surviving patients was 9.4 years. RESULTS: Tumor regrowth occurred in 60 patients, and 95% of tumors (95% confidence interval, 93%-96%) were controlled locally at 15 years. Risk scores were developed for the other 3 outcomes studied. Overall, the treated eye was retained by 84% of patients (95% confidence interval, 80%-87%) at 15 years. The probabilities for vision loss (visual acuity worse than 20/200) ranged from 100% to 20% at 10 years and for death from tumor metastases from 95% to 35% at 15 years, depending on the risk group. CONCLUSIONS: High-dose radiation treatment was highly effective in achieving local control of intraocular melanomas. In most cases, the eye was salvaged, and functional vision was retained in many patients. The mortality rate was high in an identifiable subset of patients who may benefit from adjuvant therapies directed at microscopic liver metastases.

Assessment of long-term quality of life after laparoscopic and open surgery for Crohn's disease.

OBJECTIVE: Surgery for Crohn's disease (CD) is associated with a high recurrence rate and quality of life (QOL) in these patients is controversial. The aim of this study was to assess QOL in patients after laparoscopic and open surgery for CD by two different validated instruments, a generic nonspecific score and a specific gastrointestinal QOL index. PATIENTS AND METHODS: Patients with CD who underwent elective laparoscopic or open ileocaecal resection with primary anastomosis between 1992 and 2000 were followed for recurrence and surgery-related complications. QOL was assessed by the SF-36 Health Survey containing a mental (MCS) and a physical (PCS) component summary score and by the Gastrointestinal Quality of Life Index (GIQLI) developed by Eypasch. RESULTS: Thirty-seven patients with a mean age of 48.8 +/- 18.4 years including 23 females and 14 males were evaluated at a mean follow-up of 42.6 +/-25.8 months (minimum of 8 months). Twenty-one (57%) patients underwent laparoscopic resection and 16 (43%) open surgery. Both groups were well matched for age, gender, ASA class and body mass index. Fourteen (38%) patients developed recurrent disease and 3 (8%) had postoperative incisional hernias. Overall, QOL scores were 103 +/- 26.8 for the GIQLI, 47.2 +/- 11.8 for the PCS, and 49.2 +/- 11.5 for the MCS. The GIQLI correlated well with the SF36, correlation coefficient = 0.68 for GIQLI vs PCS (95% CI, 0.41,0.95) and 0.67 for GIQLI vs MCS (95%CI, 0.39, 0.95), respectively. When compared to the general US population, mean GIQLI scores (-13.8, P = 0.002) and mean PCS scores (-4.7, P = 0.001) were significantly lower in these patients than in healthy individuals. In a multivariate analysis of impact factors on QOL, recurrence within the follow-up period was the single significant determinant reducing the PCS (-35.1, P = 0.026) and the GIQLI (-36.1, P = 0.018). CONCLUSION: QOL is significantly reduced in patients with CD at long-term follow-up after both laparoscopic and open surgery. Recurrence is the only factor adversely affecting QOL of CD patients in remission irrespective of the operative technique applied.

Total fundoplication with or without gastroplasty for gastroesophageal reflux: comparative study.

The results of clinical, radiographic, manometric, and pH-metric studies of two groups of patients with reflux esophagitis treated by total (Nissen) fundoplication with or without a Collis esophagus-lengthening gastroplasty were compared. On postoperative follow-up, clinical recurrence of gastrophageal reflux was found in 5 of the 76 patients in the Nissen group, whereas none of the 46 patients in the Collis-Nissen group had reflux. A dramatic reduction in the clinical score was observed for all patients, and postoperative clinical morbidity was similar in both groups. Postoperative radiographic recurrence of hiatal hernia was found in 11 of 60 patients in the Nissen group, but not in any of the patients in the Collis-Nissen group. The lower esophageal sphincter pressure was significantly increased after operation in both groups (p less than 0.05). The postoperative "common cavity test" and acid reflux test were positive in 9% of the patients having Nissen fundoplication alone and 11% of those having the Collis-Nissen procedure; in the latter group, both tests were positive in only 1 asymptomatic patient. These results demonstrate that the standard Nissen repair is a good surgical technique for management of uncomplicated reflux esophagitis and that the Collis-Nissen procedure is the most effective method of surgical repair for almost all patients with complicated reflux esophagitis.

Radiation therapy failure in prostate cancer patients: risk factors and methods of detection.

Radiation therapy for clinically localized prostatic carcinoma remains one of the mainstays among therapeutic approaches; however, patients continue to fail radiation therapy at too high a rate. This article reviews the risk factors and methods of detection for prostate cancer recurrence. The relative merits of the three major pre-therapy prognostic indicators-TNM staging, Gleason score, and serum prostate-specific antigen (PSA) levels-are discussed. The use of staging and Gleason score, as well as digital rectal examination, transrectal ultrasound, and post-radiation prostate biopsies in detecting failure of radiation therapy is reviewed. Challenges relating to the use of serum PSA levels as an indicator of recurrence are examined. Finally, this article makes recommendations as to procedure for evaluating patients suspected of failing radiation therapy.

Link between platelet activity and outcomes after an ischemic stroke.

BACKGROUND: Platelets play an important role in atherosclerosis and thromboembolic events. We examined the relationship between platelet activity and outcomes after an ischemic stroke. METHODS: Using flow cytometry, we serially measured the fractions of circulating platelet activity (CD62p expression) after an ischemic stroke in early (<48 h), recent (day 7), convalescent (day 21) and chronic (day 90) phases in 92 consecutive patients with an ischemic stroke. Patients were classified into high (CD62p expression >3.16%) and low (CD62p expression < or =3.16%) platelet activity groups according to the median value of CD62p expression in the early phase of a stroke. RESULTS: The composite end point--death, recurrent stroke and severe neurological impairment (alive in care), defined as a score of >13 on the National Institutes of Health Stroke Scale--within the first 30 days and at an interval of 8.2 +/- 1.5 months of follow-up was determined for each group. In the first 30 days, the composite end point occurred in 37.0% of patients in the high platelet activity group as compared with 6.5% in the low platelet activity group (p = 0.0004). At a mean follow-up of 8.2 +/- 1.5 months, the composite end point occurred in 36.6% of patients in the high platelet activity group as compared with 10.9% in the low platelet activity group (p = 0.0044). Multiple stepwise logistic regression analysis displayed that high platelet activity (p = 0.011), age (p = 0.013) and the presence of coronary artery disease (p = 0.021) were independently associated with adverse outcomes at the intermediate-term follow-up. CONCLUSIONS: Results of this study showed that high platelet activity is strongly associated with adverse clinical outcomes after an early ischemic stroke.

Liver transplantation for hepatocellular carcinoma: a proposal of a prognostic scoring system.

BACKGROUND: The current staging system of hepatocellular carcinoma established by the International Union Against Cancer and the American Joint Committee on Cancer does not necessarily predict the outcomes after hepatic resection or transplantation. STUDY DESIGN: Various clinical and pathologic risk factors for tumor recurrence were examined on 344 consecutive patients who received hepatic transplantation in the presence of nonfibrolamellar hepatocellular carcinoma to establish a reliable risk scoring system. RESULTS: Multivariate analysis identified three factors as independently significant poor prognosticators: 1) bilobarly distributed tumors, 2) size of the greatest tumor (2 to 5 cm and > 5 cm), and 3) vascular invasion (microscopic and macroscopic). Prognostic risk score (PRS) of each patient was calculated from the relative risks of multivariate analysis. The patients were grouped into five grades of tumor recurrence risk: grade 1: PRS = 0 to < 7.5; grade 2: PRS = 7.5 to < or = 11.0; grade 3: PRS > 11.0 to 15.0; grade 4: PRS > or = 15.0; and grade 5: positive node, metastasis, or margin. The proposed PRS system correlated extremely well with tumor-free survival after liver transplantation (100%, 61%, 40%, 5%, and 0%, from grades 1 to 5, respectively, at 5 years), but current pTNM staging did not. CONCLUSIONS: 1) Patients with grades 1 and 2 are effectively treated with liver transplantation, 2) patients with grades 4 and 5 are poor candidates for liver transplantation, and 3) patients with grade 1 do not benefit from adjuvant chemotherapy.

Appropriate invasive and conservative treatment approaches for patients with non-ST-elevation MI.

Compelling evidence from randomized clinical trials has established the superiority of an early invasive over a conservative management strategy in patients presenting with non-ST-segment acute coronary syndromes, with a 20% to 40% reduction in recurrent ischemic events in patients undergoing routine early angiography and revascularization when appropriate. Those patients at high risk of death, recurrent myocardial infarction, or ischemia as indicated by elevated concentrations of cardiac troponin, ST-segment deviation, or high clinical risk score derive a greater clinical benefit from early invasive management than patients at lower risk who may be managed effectively with either strategy. Patients who have recurrent ischemia, infarction, hemodynamic instability, or a high-risk stress test should be considered for urgent catheterization regardless of the initial strategy chosen.

Identification of transient and persistent segmental wall motion abnormalities in patients with unstable angina by two-dimensional echocardiography.

To determine the value of real-time, two-dimensional echocardiography (2-D echo) in unstable angina, regional wall motion on serial short-axis 2-D echo recordings was analyzed and summed segment scores of abnormal motion were compared and classified according to each patient's clinical status 12 weeks after hospital discharge. Nineteen male patients who fulfilled criteria for unstable angina and responded to medical therapy underwent 2-D echo study within 48 hours of admission and discharge. Of 11 patients with abnormal 2-D echo scores on admission, five patients had reduced scores and six patients had similar or increased scores at discharge. Six of eight patients who had scores of zero on admission had scores of zero at discharge. At follow-up, 11 patients had minimal or no angina pectoris (group 1), and eight patients had worsening angina or recurrent unstable angina (group 2). At discharge, 2-D echo studies showed that all group 1 patients had reduced or zero scores, while group 2 patients retained or increased their abnormal scores. This study shows that in patients with unstable angina, both transient and persistent abnormalities can be identified by 2-D echo. Abnormal segmental wall motion was transient or absent in patients with a good outcome, and worsened or remained abnormal in patients with a poor outcome.

Hepatitis C recurrence is more severe after living donor compared to cadaveric liver transplantation.

Preliminary reports suggested that hepatitis C virus (HCV) infection has a more aggressive course following living donor liver transplantation (LDLT) compared to cadaveric liver transplantation (CLT). The aim of this prospective study was to establish if HCV disease recurrence differs between LDLT and CLT. A cohort of 116 consecutive HCV-infected patients undergoing 117 LTs in a single center from March 2000 to August 2003 were followed-up, including systematic liver biopsies. Severe recurrence (SR) was defined as biopsy-proven cirrhosis and/or the occurrence of clinical decompensation. After a median follow-up of 22 months (2.6-44 months), 26 (22%) patients developed SR (decompensation in 12), involving 17 (18%) of 95 patients undergoing CLT and 9 (41%) of 22 undergoing LDLT. The 2-year probability of presenting SR was significantly higher in LDLT compared to CLT (45% vs. 22%, P = .019). By univariate analysis LDLT (P = .019) and an ALT higher than 80 IU/L 3 months after LT (P = .022) were predictors of SR. In 93 patients from whom a liver biopsy was available 3 months after LT, a lobular necroinflammatory score >1 (P < .01), LDLT (P < .01), and biliary complications (P = .046) were associated with SR. However, the only variables independently associated with SR were LDLT (odds ratio [OR], = 2.8; 95% CI,1.19-6.6; P = .024) and a lobular necroinflammatory score > 1 (OR, 3.1; 95% CI, 1.2-8; P = .013). In conclusion, HCV recurrence is more severe in LDLT compared to CLT. Although our results were based on a single-center experience, they should be considered in the decision-making process of transplant programs, since severe HCV recurrence may ultimately compromise graft and patient survival.

Beneficial effects of diltiazem during myocardial reperfusion: a randomized trial in acute myocardial infarction.

BACKGROUND: Although in experimental models of coronary occlusion diltiazem administration has been shown to reduce the degree of stunning and of reperfusion injury, the majority of clinical trials has failed to demonstrate significant benefits. The aim of this study was to evaluate the effect of diltiazem, administered before coronary reperfusion, on infarct size, residual myocardial viability and recovery of left ventricular function. METHODS: We studied 90 patients admitted within 3 hours of the onset of symptoms of acute myocardial infarction. They were immediately randomized to either intravenous diltiazem (10 mg bolus + 10 mg/hour for 3 days) (group 1, n = 43) or placebo (group 2, n = 47) and subsequently treated with recombinant tissue-type plasminogen activator. All underwent serial echocardiograms upon admission, 4 days post-admission during low-dose dobutamine stress echo, at discharge and after 6 months. We calculated the dysfunction score (1 = hypokinesia, 2 = akinesia, 3 = dyskinesia) on admission and its percent reduction after dobutamine (viability) and at follow-up (recovery). The 12-lead electrocardiograms were continuously monitored for 3 days and coronary angioplasty was performed whenever the residual stenosis was > 60%. RESULTS: Upon admission, there were no differences in age, sex, infarct location and size, degree of ST-segment elevation, time from onset of symptoms and dysfunction score. Creatine kinase peaked early in 70% of patients in both groups; the incidences of recurrent ischemia, infarct-related vessel patency and the need for coronary angioplasty were also similar. The creatine kinase peak was significantly higher in group 2 (2931 +/- 2456 vs 1726 +/- 1004 IU/l, p < 0.05). Conversely, in group 1 the residual viability was significantly higher (51 +/- 23 vs 36 +/- 30% improvement in dysfunction score, p < 0.05) and the early recovery of regional function was significantly greater (35 +/- 34 vs 18 +/- 22% at discharge, p < 0.05). On the other hand, the delayed recovery was not significantly different (15 +/- 29 vs 21 +/- 32% from the time of discharge to 6 months of follow-up). CONCLUSIONS: Intravenous diltiazem, started before coronary reperfusion, has beneficial effects on the infarct size, residual viability and recovery of regional function. If confirmed by larger trials, these preliminary results suggest the use of diltiazem as adjunctive therapy in patients with acute myocardial infarction and undergoing reperfusion.
