Long-term impact of multivessel disease on cause-specific mortality after ST elevation myocardial infarction treated with reperfusion therapy.

OBJECTIVES: To investigate the long-term impact of multivessel coronary artery disease (MVD) on cause-specific mortality in patients with ST elevation myocardial infarction (STEMI) treated with reperfusion therapy. METHODS AND RESULTS: Patients with STEMI (n = 395) treated with primary angioplasty or thrombolysis in the setting of a randomised clinical trial were enrolled in the study. Follow up was 8 (2) years. For patients who died all available records were reviewed to assess the specific cause of death. MVD was present in 57% of patients. Patients with MVD were older and more of them had diabetes and previous myocardial infarction. Compared with the non-MVD group, residual left ventricular ejection fraction was lower (45.9% v 49.6%, p = 0.001) and total mortality was higher in patients with MVD (32% v 19%, p = 0.002). After adjustment for potential confounders this association was not significant (hazard ratio 1.4, 95% confidence interval (CI) 0.9 to 2.2). When the specific cause of death was considered, sudden death was comparable between patients with and without MVD (10% v 8%, p = 0.49) but death caused by heart failure was significantly higher in patients with MVD (hazard ratio 7.4, 95% CI 1.7 to 32.2). CONCLUSION: Patients with STEMI and MVD have a higher long-term mortality than do patients with non-MVD. MVD is not an independent predictor of long-term total mortality or sudden death. However, MVD is a very strong and independent predictor of long-term death caused by heart failure.

Prognostic value of admission glucose and glycosylated haemoglobin levels in acute coronary syndromes.

BACKGROUND: Admission hyperglycaemia is associated with poorer prognosis in patients with an acute coronary syndrome (ACS). Whether hyperglycaemia is more important than prior long-term glucose metabolism, is unknown. AIM: To investigate the prognostic value of admission glucose and HbA(1c) levels in patients with ACS. METHODS: We measured glucose and HbA(1c) at admission in 521 consecutive patients with suspected ACS. Glucose was categorized as <7.8 (n = 305), 7.8-11.0 (n = 138) or > or =11.1 mmol/l (n = 78); HbA(1c) as <6.2% (n = 420) or > or =6.2% (n = 101). Mean follow-up was 1.6 +/- 0.5 years. RESULTS: The diagnosis of ACS was confirmed in 332 patients (64%), leaving 189 (36%) with atypical chest pain. In ACS patients, mortality by glucose category (<7.8, 7.8-11.0 or > or =11.1 mmol) was 9%, 8% and 25%, respectively (p = 0.001); mortality by HbA(1c) category (<6.2% vs. > or =6.2%) was 10% vs. 17%, respectively (p = 0.14). On multivariate analysis, glucose category was significantly associated with mortality (HR 3.0, 95% CI 1.1-8.3), but HbA(1c) category was not (HR 1.5, 95%CI 0.6-4.2). DISCUSSION: Elevated admission glucose appears more important than prior long-term abnormal glucose metabolism in predicting mortality in patients with suspected ACS.

Long-term clinical outcome of patients with diabetes proposed for coronary revascularisation.

BACKGROUND: The optimal method of revascularisation in diabetic patients with coronary artery disease (CAD) remains controversial. It was our aim to evaluate long-term outcome in diabetic patients with CAD in daily practice, in whom an invasive approach was considered. METHODS: A prospective follow-up study of patients with CAD in whom a coronary revascularisation procedure was considered. Follow-up data were obtained on the vital status up to ten years after inclusion. RESULTS: Of the 872 included patients, a total of 107 patients (12%) had diabetes. Patients with diabetes were older and more frequently female. Long-term mortality was higher in diabetics than nondiabetics (36 vs 25%, p = 0.01). This association was observed in both medically treated patients (65 vs 31%, p = 0.01) and in those treated by percutaneous coronary intervention (41 vs 24%, p = 0.02). There was, however, no difference in mortality in diabetes vs nondiabetes patients after coronary artery bypass grafting (24 vs 24%, p = 0.89). Multivariate analysis did not change these findings. CONCLUSION: Diabetic patients with significant CAD had a higher long-term mortality compared with patients without diabetes. In patients with diabetes, survival was highest after coronary artery bypass grafting and appeared to be comparable between diabetic and nondiabetic patients. Complete revascularisation may decrease the influence of diabetes on survival.

Primary percutaneous coronary intervention versus thrombolytic treatment: long term follow up according to infarct location.

OBJECTIVES: To study the clinical significance of infarct location during long term follow up in a trial comparing thrombolysis with primary angioplasty. DESIGN: Retrospective longitudinal cohort analysis of prospectively entered data. SETTING: Patients with acute ST elevation myocardial infarction (STEMI) treated with primary percutaneous coronary intervention (PCI). PATIENTS: In the Zwolle trial 395 patients with acute STEMI were randomly assigned to intravenous streptokinase or PCI. MAIN OUTCOME MEASURES: Survival according to infarct location and treatment after 8 (2) years of follow up. RESULTS: 105 patients died: 63 patients in the streptokinase group and 42 patients in the primary PCI group (relative risk (RR) 1.6, 95% confidence interval (CI) 1.0 to 2.6; p = 0.03). In patients with non-anterior STEMI there was no difference in mortality between streptokinase and PCI treated patients (RR 1.1, 95% CI 0.6 to 2.1; p = 0.68) but the streptokinase group had significantly more major adverse cardiac events (MACE) than the PCI group (RR 2.1, 95% CI 1.2 to 3.6). The number needed to treat to prevent one MACE was four. In patients with anterior STEMI, mortality was higher in the streptokinase group than in the PCI group (RR 2.7, 95% CI 1.4 to 5.5; p = 0.004). The number needed to treat to prevent one death was five. Kaplan-Meier analysis confirmed the benefits of primary angioplasty in the first year and showed additional benefit of PCI compared with streptokinase between 1-8 years after the acute event. CONCLUSIONS: Patients with anterior STEMI have better long term survival when treated with PCI than with streptokinase. In patients alive one year after the acute event, PCI confers a significant additional survival benefit, probably due to better preserved residual left ventricular function.

Dysglycemia in suspected acute coronary syndromes.

BACKGROUND: Apart from diabetes itself, even minor glycometabolic dysregulation may be associated with an increased risk of cardiovascular disease. We analyzed the prevalence and predictive value of glycometabolic disturbances in patients with a suspected acute coronary syndrome (ACS). METHODS: In a prospective follow-up study, admission glucose and Hba1C levels in all consecutive patients with suspected ACS were measured. Dysglycemia was defined as a Hba1C of 5.6-6.1% with a non-fasting glucose above 7.8 mmol/L. Both predictors of glycometabolic disturbances and the predictive value of glycometabolic disturbances were studied. RESULTS: Of the 521 patients with a suspected ACS who were included in the study, 332 (64%) had an ACS and 189 (36%) had atypical chest pain. A total of 115 patients (22%) had diabetes and 65 (13%) had dysglycemia. Patients with diabetes or dysglycemia had an increased risk of a confirmed diagnosis of ACS (RR 2.3, 95% CI 1.5-3.4). Multivariate analyses did not change these findings. CONCLUSIONS: One in three patients with suspected ACS had a glucose metabolism disturbance. Glycometabolic disturbance was strongly associated with a confirmed diagnosis of ACS. Whether intensive treatment of patients with disturbed glucose metabolism may improve long-term prognosis needs to be assessed.

Prognostic value of erythrocyte sedimentation rate in ST segment elevation myocardial infarction: interaction with hyperglycaemia.

OBJECTIVES: Many inflammatory markers are associated with an adverse prognosis after ST segment elevation myocardial infarction (STEMI). Hyperglycaemia may exacerbate this inflammatory response. We investigated whether the erythrocyte sedimentation rate (ESR) was associated with an adverse prognosis and whether this was mediated by glucose levels. RESEARCH DESIGN AND METHODS: It concerns a post hoc analysis of a prospective randomised trial. In 346 patients with STEMI treated with reperfusion therapy, we investigated long-term outcome. Patients with ESR in the upper quartile (>14 mm h(-1)) were compared to patients with a normal ESR. Hyperglycaemia was defined as admission glucose >or=7.8 mmol L(-1). Median follow up was 7.4 years (range: 5.7-8.3). MAIN OUTCOME MEASURES: All cause mortality, cardiovascular mortality, sudden death, death as a result of heart failure. RESULTS: Both elevated ESR and hyperglycaemia were associated with a worse prognosis and increased mortality. Elevated ESR was particularly associated with an increased risk of sudden death (OR: 3.3, 17% vs. 6%, P < 0.01) whereas hyperglycaemia was especially associated with an increased risk of death because of heart failure (OR: 6.5, 8% vs. 1%, P < 0.01). There was no association between increased ESR and elevated glucose levels. Multivariate analysis did reveal that both elevated ESR and admission glucose were independent predictors of long-term mortality. CONCLUSIONS: Elevated ESR and admission glucose are independent predictors of mortality in STEMI patients treated with reperfusion therapy. There is no association or interaction between glucose levels and the inflammatory response as reflected by ESR.

Is routine stenting for acute myocardial infarction superior to balloon angioplasty? A randomised comparison in a large cohort of unselected patients.

OBJECTIVE: To evaluate the impact of routine stenting, compared with balloon angioplasty, in unselected patients presenting with ST segment elevation myocardial infarction (STEMI). DESIGN: Randomised trial. SETTING: Tertiary referral centre. PARTICIPANTS: All patients presenting with STEMI randomly assigned to stenting or balloon angioplasty. No exclusion criteria were applied. MAIN OUTCOME MEASURE: The primary end point was combined death or reinfarction at one year's follow up. RESULTS: 1683 consecutive patients with STEMI were randomly assigned before angiography to stenting (n = 849) or balloon angioplasty (n = 834). A total of 785 patients (92.5%) in the stent group and 763 patients (91.5%) in the balloon group actually underwent primary angioplasty. The groups were comparable in terms of postprocedural TIMI (thrombolysis in myocardial infarction) flow, myocardial blush grade, and distal embolisation. No difference was observed in clinical outcome at both intention to treat (14% v 12.5%, not significant) and actual treatment analyses (12.4% v 11.3%, not significant). CONCLUSIONS: Compared with balloon angioplasty, routine stenting does not seem to reduce death and reinfarction in a large cohort of unselected patients with STEMI.

Association of revascularisation with low mortality in non-ST elevation acute coronary syndrome, a report from GUSTO IV-ACS.

BACKGROUND: Immediate, as well as early, revascularisation is of benefit in patients with acute coronary syndromes (ACS) presenting with ST elevation. However, trials comparing invasive versus medical treatment in patients with an acute coronary syndrome without ST elevation do not consistently show improvement in survival after revascularisation. Accordingly, additional data are warranted. METHODS: The effect of revascularisation within 30 days on one-year survival in the GUSTO IV ACS trial was investigated. A total of 7800 patients were included with an acute coronary syndrome without ST elevation, documented by either elevated cardiac troponin or transient or persistent ST-segment depression. In this trial, comparing abciximab versus placebo as initial medical therapy, coronary angiography within 60 h after randomisation was discouraged. In 30-day survivors, those who underwent revascularisation were compared with 30-day survivors without revascularisation. Adjustments were made for patient characteristics, and for a propensity score that was adjusted for covariates associated with the likelihood of early revascularisation. FINDINGS: Of the 7496 patients who survived at least 30 days, 2265 (30%) underwent coronary revascularisation within 30 days: 789 patients CABG, 1450 PCI and 26 both CABG and PCI. Procedure-related mortality was low at 1.8%. Patients with revascularisation had a lower one-year mortality compared to medically treated patients (2.3% vs. 5.6%, p < 0.001). After multivariable analyses, patients with revascularisation had a relative risk of subsequent mortality within 1 year of 0.53 (95% CI 0.37-0.77) compared to patients without revascularisation. CONCLUSIONS: Revascularisation within 30 days is associated with an improved prognosis in ACS without ST-segment elevation. The relative high mortality in medically treated patients may be related in part to patient selection, but warrants further studies to improve outcome of these patients.

Long-term results after the glycoprotein IIb/IIIa inhibitor abciximab in unstable angina: one-year survival in the GUSTO IV-ACS (Global Use of Strategies To Open Occluded Coronary Arteries IV--Acute Coronary Syndrome) Trial.

BACKGROUND: This study was designed to investigate long-term effects of the glycoprotein IIb/IIIa inhibitor abciximab in patients with acute coronary syndrome without ST elevation who were not scheduled for coronary intervention. METHODS AND RESULTS: A total of 7800 patients were included with an acute coronary syndrome without ST elevation, documented by either elevated cardiac troponin or transient or persistent ST-segment depression. They were randomized to abciximab bolus and 24-hour infusion, abciximab bolus and 48-hour infusion, or matching placebo. The overall 1-year mortality rate was 8.3% (649 patients). One-year mortality was 7.8% in the placebo group and 8.2% in the 24-hour and 9.0% in the 48-hour abciximab infusion group. Compared with placebo, the hazard ratio for the 24-hour infusion of abciximab was 1.1 (95% CI 0.86 to 1.29), and for the 48-hour infusion, it was 1.2 (95% CI 0.95 to 1.41). The lack of benefit of abciximab was observed in every subgroup studied. Patients with negative troponin or elevated C-reactive protein had a higher mortality rate after treatment with abciximab for 48 hours than with placebo: 8.5% versus 5.8% in those with negative troponin (P=0.02), 16.3% versus 12.1% in those with elevated C-reactive protein (P=0.04). CONCLUSIONS: Compared with placebo, abciximab did not provide any survival benefit at 1 year in patients admitted with an acute coronary syndrome with ST depression and/or elevated troponin who were not scheduled to undergo early coronary revascularization. In subgroups of patients, in particular those with low cardiac troponin or elevated C-reactive protein, abciximab was associated with excess mortality.

[Percutaneous insertion of a left ventricular assist device for cardiogenic shock in a patient with a myocardial infarction].

A 54-year-old man who was admitted due to cardiogenic shock as a result of a large anterior myocardial infarction 3 days previously was about to die, despite reperfusion therapy, application of an intra-aortic balloon pump, mechanical ventilation and maximal medical therapy. After insertion of a percutaneous left ventricular assist device, the patient was haemodynamically stable. After 11 days, the assist device was weaned and was removed. One day later, the patient died due to progressive heart failure. This case shows that a percutaneously inserted left ventricular assist device is effective in patients with severe, refractory cardiogenic shock, and is relatively simple to insert in the heart catheterisation room. However, it is still not clear what the recovery possibilities of the heart are following a large myocardial infraction, which factors may influence this recovery, and what the applicability of such a ventricular assist device might be in bridging the recovery period.

Incidence and clinical significance of distal embolization during primary angioplasty for acute myocardial infarction.

AIMS: Although recognized as an important feature of atherosclerotic coronary disease, little is known about the frequency and prognostic importance of distal embolization during primary angioplasty for acute myocardial infarction. METHODS AND RESULTS: As part of a randomized trial of thrombolysis vs primary angioplasty, 178 patients with acute myocardial infarction were treated with primary angioplasty. In these patients the occurrence of distal embolization after angioplasty was assessed. Embolization was defined as a distal filling defect with an abrupt 'cutoff' in one of the peripheral coronary artery branches of the infarct-related vessel, distal to the site of angioplasty. We analysed myocardial blush grade, ST-T segment elevation resolution, enzymatic infarct size and left ventricular ejection fraction in patients with and without distal embolization. Clinical information was collected for a mean of 5 years. Distal embolization was present in 27 patients (15.2%). Mean age and gender were not different from patients without distal embolization. Angiographic success (thrombolyis in myocardial infarction flow grade 3 and residual stenosis <50%) after primary angioplasty was less frequently observed in patients with distal embolization (70% vs 90%, P<0.01). Myocardial blush and ST-T segment elevation resolution after angioplasty were reduced when distal embolization was present. Patients with distal embolization had a larger enzymatic infarct size (mean cumulative lactate dehydrogenase measured over 72 h, 1612 vs 847, P<0.05) and a lower left ventricle ejection fraction at discharge (42% vs 51%, P<0.01). Long-term mortality was higher in patients with distal embolization (44% vs 9%, P<0.001). CONCLUSION: Distal embolization in patients treated with primary angioplasty is visible on the coronary angiogram in 15.2% of patients. It is related to reduced myocardial reperfusion, more extensive myocardial damage and a poor prognosis. Additional pharmacological interventions and/ or mechanical devices should be studied to prevent and/or treat distal embolization.

A bleeding disorder caused by a cardiac tumor: case report.

A 22-year-old female developed symptomatic thrombocytopenia. On physical examination, apart from ecchymoses, a loud holosystolic murmur was heard. Echocardiography revealed a cardiac tumor. The thrombocytopenia did not respond to corticosteroids, but after surgical removal of the intracardiac tumor, a papillary fibroelastoma, the platelet count normalised. There are no similar case reports in the literature. Our case report illustrates that thrombocytopenia may be associated with a cardiac tumor and that complete physical examination is essential in every patient presenting with easy bruising.

Long-term recovery of left ventricular function after primary angioplasty for acute myocardial infarction.

AIMS: To investigate changes in left ventricular function in the first 6 months after acute myocardial infarction treated with primary angioplasty. To assess clinical variables, associated with recovery of left ventricular function after acute myocardial infarction. METHODS: Changes in left ventricular function were studied in 600 consecutive patients with acute myocardial infarction, all treated with primary angioplasty. Left ventricular ejection fraction was measured by radionuclide ventriculography in survivors at day 4 and after 6 months. Patients with a recurrent myocardial infarction within the 6 months were excluded. RESULTS: Successful reperfusion (TIMI 3 flow) by primary angioplasty was achieved in 89% of patients. The mean ejection fraction at discharge was 43.7%+/-11.4, whereas the mean ejection fraction after 6 months was 46.3%+/-11.5 (P<0.01). During the 6 months, the mean relative improvement in left ventricular ejection fraction was 6%. An improvement in left ventricular function was observed in 48% of the patients; 25% of the patients had a decrease, whereas in the remaining patients there was no change. After univariate and multivariate analysis, an anterior infarction location, an ejection fraction at discharge < or =40% and single-vessel disease were significant predictors of left ventricular improvement during the 6 months. CONCLUSIONS: After acute myocardial infarction treated with primary angioplasty there was a significant recovery of left ventricular function during the first 6 months after the infarction. An anterior myocardial infarction, single-vessel coronary artery disease, and an initially depressed left ventricular function were independently associated with recovery of left ventricular function. Multivessel disease was associated with absence of functional recovery. Additional studies, investigating complete revascularization are needed, as this approach may potentially improve long-term left ventricular function.

Long term outcome and cost-effectiveness of stenting versus balloon angioplasty for acute myocardial infarction.

OBJECTIVE: To investigate the long term clinical outcome and cost-effectiveness of stenting compared with balloon angioplasty in patients with acute myocardial infarction. METHODS: Patients with acute myocardial infarction were randomly allocated to primary stenting (112) or balloon angioplasty (115). The primary end point was the cumulative first event rate of death, non-fatal reinfarction, or target vessel revascularisation. Secondary end points were restenosis at six months and the cost-effectiveness at follow up. RESULTS: After 24 months, the combined clinical end point of death/reinfarction was 4% after stenting and 11% after balloon angioplasty (p = 0.04). Subsequent target vessel revascularisation was necessary in 15 patients (13%) after stenting and in 39 (34%) after balloon angioplasty (p < 0.001). The cumulative cardiac event-free survival rate was also higher after stenting (84% v 62%, p < 0.001). The angiographic restenosis rate after stenting was less than after balloon angioplasty (12% v 34%, p < 0.001). Despite the higher initial costs of stenting (Dfl 21 484 v Dfl 18 625, p < 0.001), the cumulative costs at 24 months were comparable with those of balloon angioplasty (Dfl 31 423 v Dfl 32 933, p = 0.83). CONCLUSIONS: Compared with balloon angioplasty, primary stenting for acute myocardial infarction results in a better long term clinical outcome without increased cost.

High dose heparin as pretreatment for primary angioplasty in acute myocardial infarction: the Heparin in Early Patency (HEAP) randomized trial.

OBJECTIVES: In the Heparin in Early Patency (HEAP) pilot study a beneficial effect of high-dose heparin on early patency in acute myocardial infarction (MI) was observed in a matched-control study. BACKGROUND: High dose bolus intravenous injection of heparin may achieve lysis of coronary thrombi and could enhance early patency of the infarct related vessel in patients with MI scheduled for primary angioplasty. METHODS: Before primary angioplasty, 584 patients with MI entered an open randomized trial of high dose (300 IU/kg) or low dose (0 or 5,000 IU) heparin. Of the 584 patients, 299 were randomized to high dose and 285 patients to low dose heparin. RESULTS: Thrombolysis In Myocardial Infarction (TIMI) flow grade 2 or 3 was observed before primary angioplasty in 65 patients (22%) in the high dose group and 60 patients (21%) in the low dose heparin group (p > 0.1), whereas TIMI flow grade 3 was observed in 38 (13%) and 24 patients (9%), respectively (p = 0.11). There were no differences in the clinical end points between the two groups. There were no hemorrhagic strokes, while 10% of the patients in the high dose group required blood transfusion versus 6% in the low dose/no heparin group (p = 0.07). No subsets of patients showed beneficial effects of high dose heparin, such as patients with longer delay between heparin administration and diagnostic angiogram or patients with short delay between symptom onset and admission. CONCLUSIONS: There is no benefit of high dose bolus heparin on early patency compared with no or low dose heparin.

Long-term benefit of primary angioplasty as compared with thrombolytic therapy for acute myocardial infarction.

BACKGROUND: As compared with thrombolytic therapy, primary coronary angioplasty results in a higher rate of patency of the infarct-related coronary artery, lower rates of stroke and reinfarction, and higher in-hospital or 30-day survival rates. However, the comparative long-term efficacy of these two approaches has not been carefully studied. METHODS: We randomly assigned a total of 395 patients with acute myocardial infarction to treatment with angioplasty or intravenous streptokinase. Clinical information was collected for a mean (+/-SD) of 5+/-2 years, and medical charges associated with the two treatments were compared. RESULTS: A total of 194 patients were assigned to undergo primary angioplasty, and 201 to receive streptokinase. Mortality was 13 percent in the angioplasty group, as compared with 24 percent in the streptokinase group (relative risk, 0.54; 95 percent confidence interval, 0.36 to 0.87). Nonfatal reinfarction occurred in 6 percent and 22 percent of the two groups, respectively (relative risk, 0.27; 95 percent confidence interval, 0.15 to 0.52). The combined incidence of death and nonfatal reinfarction was also lower among patients assigned to angioplasty than among those assigned to streptokinase, with a relative risk of 0.13 (95 percent confidence interval, 0.05 to 0.37) for early events (within the first 30 days) and a relative risk of 0.62 (95 percent confidence interval, 0.43 to 0.91) for late events (after 30 days). The rates of readmission for heart failure and ischemia were also lower among patients in the angioplasty group than among patients in the streptokinase group. Total medical charges per patient were lower in the angioplasty group (16,090 dollars) than in the streptokinase group (16,813 dollars, P=0.05). CONCLUSIONS: During five years of follow-up, primary coronary angioplasty for acute myocardial infarction was associated with lower rates of early and late death and nonfatal reinfarction, fewer hospital readmissions for ischemia or heart failure, and lower total medical charges than treatment with intravenous streptokinase.

[Prevalence of asymptomatic cardiac ischemia in men with diabetes mellitus type I].

OBJECTIVE: To establish the prevalence of 'silent ischaemia' of the myocardium in male patients with type 1 diabetes mellitus using a non-invasive cardiac examination, and to determine what clinical variables are related to silent ischaemia. DESIGN: Prospective, cross-sectional. METHOD: Males aged 20-69 years who visited the outpatient department of Internal Medicine of the De Weezenlanden Hospital in Zwolle between 1 February 1992 and 31 January 1995, and who showed no symptoms of ischaemic cardiopathy (angina pectoris, myocardial infarction or arrhythmias) or of chronic obstructive pulmonary disease, were examined for cardiac ischaemia by means of a 24-hour Holter registration and a perfusion scintigram after administration of dipyridamol. In order to demonstrate a possible connection between cardiovascular risk factors and silent ischaemia, the patients with an abnormal and those with a normal scintigram were compared by means of multivariate analysis. RESULTS: Data were collected on 92 successive patients, with a median age of 40 years (range 22-69). There were 19 patients (21%) with an abnormal myocardial scintigram. On average they were older and had a longer history of diabetes mellitus. An abnormal Holter registration was observed in 14 patients (15%), abnormality of either the Holter registration or the myocardial scintigram in 28 patients (30%) and abnormality of both the myocardial scintigram and the Holter registration in 5 patients (5%). The duration of the diabetes mellitus, and a diastolic blood pressure > or = 90 mm Hg were statistically significant and independent predictors of an abnormal myocardial scintigram (relative risks 1.08 and 3.4 per year, respectively). CONCLUSIONS: The prevalence of cardiac ischaemia in males with type 1 diabetes mellitus without cardiac symptoms is approximately 20%. Abnormal test results were associated with a longer duration of the diabetes mellitus and a diastolic blood pressure > or = 90 mm Hg.
