Predictors of left ventricular dilatation in young adults (from the Bogalusa Heart Study).

Left ventricular (LV) dilatation may be an early sign of cardiac decompensation progressing to LV dysfunction. Determinants of LV dilatation in young asymptomatic adults are unknown. Five hundred six asymptomatic subjects (mean age 32 +/- 3 years) enrolled in the Bogalusa Heart Study underwent echocardiographic examination. LV dilatation (LV end-diastolic diameter >5.5 cm) as measured by M-mode echocardiography was found in 31 subjects (6%). Subjects with LV dilatation had greater body mass indexes (32 +/- 9 vs 27 +/- 6 kg/m2, p <0.0001), systolic (119 +/- 15 vs 112 +/- 12 mm Hg, p = 0.007) and diastolic (79 +/- 12 vs 75 +/- 9 mm Hg, p = 0.04) blood pressures, and LV mass (230 +/- 50 vs 123 +/- 39 g, p <0.0001). Age, gender, race, and metabolic parameters (glucose, insulin, and lipoprotein levels) did not differ significantly between the subjects with and without LV dilatation. After correction for age, gender, and race differences, adulthood obesity (body mass index >30 kg/m2) was associated with a threefold odds ratio (2.9, 95% confidence interval 1.4 to 6.1), and hypertension (defined as per the Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure) was also associated with a threefold odds ratio (3.0, 95% confidence interval 1.2 to 7.1) for an increased incidence of LV dilatation. There was an incremental increase in LV end-diastolic dimension depending on the presence of hypertension or obesity, and subjects with obesity and hypertension in adulthood had the greatest degree of LV end-diastolic dimensions. In multiple regression analyses, body mass index in childhood was the only significant predictor of LV dilatation in adulthood (odds ratio 1.47, 95% confidence interval 1.03 to 2.09). In conclusion, obesity beginning in childhood and obesity and hypertension in young adulthood are predictors of LV dilatation in an otherwise healthy young adult population.

Papillary fibroelastoma of mitral papillary chordae in a young patient.

Our case is a 38-year-old man, admitted to Cardiology Department with shortness of breath. Echocardiography yields a hyperechogenic mass localized to papillary muscle with severe mitral regurgitation. Coronary angiography demonstrated radiopacity localized to the papillary muscle. The excision of the mass was consistent with elastic tumor, which was reported as papillary fibroelastoma attached to the papillary chordae of the mitral valve. A 29 no St-Jude bileaflet mechanical valve was implanted to mitral position. Papillary fibroelastoma (PF) can be found in young age and originate from the papillary muscle, which the radiopaque angiographic appearance of the mass supports the diagnosis.

Aortic elastic properties in young pregnant women.

This study aimed to investigate the aortic elastic properties of young pregnant women by comparing them with those of age-matched healthy females. The study group consisted of 21 pregnant women at a mean age of 26 +/- 1 years; 22 healthy women at a mean age of 25 +/- 1 years constituted the control group. Doppler-color echocardiographic variables and serum estradiol (E2) levels were measured from both groups. The blood samples were obtained from the control group in the first week after menstrual bleeding. Diastolic and systolic blood pressure (DBP and SBP, respectively) were measured with a sphygmomanometer. Systolic and diastolic aortic diameters (AOS and AOD, respectively) were measured 3 cm proximal to the aortic valves. Aortic elastic properties were assessed according to the following formulas: 1, Aortic strain = (AOS - AOD)/AOD; 2, Aortic distensibility = 2 x (AOS - AOD)/(PP x AOD); 3, Aortic diameter change = AOS - AOD; 4, Aortic stiffness index = ln(SBP/DBP)/(AOS - AOD)/AOD. The results were expressed as mean +/- standard deviation and compared by t-test between groups. P < 0.05 was considered as statistically significant. All women in the study group were in their first pregnancy and second trimester. The height and weight were 160 +/- 5 vs 164 +/- 6 cm and 60 +/- 9 vs 54 +/- 3 kg in the study vs control groups, respectively (P < 0.05). The AOD was 26 +/- 3 vs 26 +/- 4 mm and AOS 29 +/- 3 vs 28 +/- 4 mm. Pulse pressure was 43 +/- 3 vs 45 +/- 8 mmHg in the study vs control groups, respectively (P > 0.05). The serum E2 level was significantly higher in pregnant women (21 300 +/- 2 300 pg/ml). Derived aortic elastic properties in pregnant women were also increased significantly (P < 0.0005). The indexes of aortic elastic properties are altered and aortic stiffness is decreased among young pregnant women. This may be due to the adaptation mechanisms including high estradiol levels detected in pregnancy.

Comorbidity of constrictive pericarditis and hemophilia A.

OBJECTIVE: To report a case of comorbidity of constrictive pericarditis and hemophilia A. CLINICAL PRESENTATION AND INTERVENTION: A 21-year-old male with hemophilia A was referred to our clinic and was examined with the subsequent evaluation of shortness of breath, leg edema and ascites. Clinical and laboratory examinations were performed. The results were consistent with constrictive pericarditis (CP), and the symptoms were completely relieved following institution of medical therapy. CONCLUSION: Because hemophilia A and pericarditis may be coincidentally present clinical conditions, avoidance of surgical procedures in hemophilic patients is preferable unless the resolution of the symptoms of pericarditis cannot be effected by medical therapy.

The effects of lipid-lowering therapy on graft patency in coronary bypass surgery patients.

BACKGROUND: Our aim was to investigate the effects of lipid-lowering treatment (LLT) on graft patency in coronary artery bypass grafting (CABG) patients. METHODS: A total of 209 CABG patients (95 men, 45%) with a total cholesterol level above 200 mg/dL and a low-density lipoprotein level above 100 mg/dL were included. Patients were divided into 2 groups on the basis of administration of LLT after CABG: group 1 received LLT after the operation (those patients undergoing operations after 1998, n = 102, 49% male) and group 2 did not receive LLT after the operation (those patients undergoing operations between 1992 and 1998, n = 107, 42% male). Median duration of follow-up was 5.2 years. Follow-up angiography could be obtained in 108 (52%) patients (56 in group 1, 52 in group 2). RESULTS: There was a 42% reduction in ischemic events and deaths in group 1, and 60% of these patients had a symptom-free or event-free period for 6 years. The 5-year graft patency for left internal mammary artery-to-left anterior descending artery grafts in group 1 was 95%, and the corresponding figure was 90% in group 2. Right coronary artery-to-saphenous vein graft patency was 66% for group 1 and 30% for group 2. Circumflex artery-to-saphenous vein patency rate was 59% for group 1 and 53% for group 2. A higher graft patency was found in group 1 as a whole. CONCLUSION: Results of this retrospective study support the fact that LLT provides a higher graft patency for CABG patients.

Noncompaction of ventricular myocardium involving both ventricles.

AIM: We aimed to present a case with ventricular myocardial noncompaction involving both ventricles. METHODS AND RESULTS: Noncompaction of ventricle is a rare and unclassified congenital cardiac malformation is due to an arrest in intrauterine endomyocardial morphogenesis. We presented a ventricular myocardial noncompaction case involving both left and right ventricles. The physical examination of this case is consistent with mitral regurgitation and the echocardiographic findings are consistent with noncompaction of ventricular myocardium involving both ventricles with left ventricular systolic failure. CONCLUSION: Transthoracic echocardiography is a useful clinical tool for diagnosing noncompaction of both the right and left ventricular myocardium. The LVNC definition can also be utilized for RVNC, which this diagnosis has never been reported in a Turkish patient.

Partial atrial standstill: a case report.

Twelve-lead electrocardiograms revealed no atrial activity and a wide QRS escape rhythm at 38 beats/min in a 20-year-old man who presented with syncope. Doppler echocardiography documented the absence of A wave both in the tricuspid and mitral valve flow. The only mechanical activity was documented at the left atrial appendage. An electrophysiologic study demonstrated electrical inactivity in the right atrium and an atrial tachycardia in the left atrium. Atrial pacing with maximum output did not capture the atria. Our case represents an advanced stage of partial atrial standstill, with a mechanical and electrical atrial activity confined only to the left trial appendage. The patient remained asymptomatic after receiving a VVIR pacemaker and anticoagulation therapy.

[Short-term effect of nebivolol on the left ventricular diastolic function].

OBJECTIVE: To determine the effects of nebivolol on diastolic functions of the left ventricle in the hypertensive patients in the early treatment period. METHODS: Twenty patients with mild to moderate hypertension taking daily 5 mg of nebivolol were assessed by using Doppler echocardiography before and after 6-week drug treatment period. The results were analyzed with Wilcoxon test and p<0.05 was accepted as statistically significant value. RESULTS: The arterial blood pressure and heart rate of the patients significantly decreased after 6 weeks of treatment. Statistically significant decrease was found in the peak of A wave velocity, isovolumetric relaxation time, E wave deceleration time and increase in E/A ratio with Doppler echocardiography after 6-week treatment period. No statistically significant difference was observed in the peak velocity of E wave after treatment period. CONCLUSION: We found that nebivolol improved left ventricular diastolic function in patients with hypertension in the early term.

A clinic investigation into prehospital and emergency department delays in acute stroke care.

OBJECTIVE: The aim of our study was to investigate the factors which cause prehospital and emergency department (ED) delays in acute stroke care. SUBJECTS AND METHODS: We prospectively studied 229 acute stroke patients (median age: 71 +/- 19 years, 90 female and 139 male) who presented to the ED of the Gulhane Military Teaching Hospital, Istanbul, Turkey. Prehospital delay was defined as time from symptom onset to arrival at the ED. Emergency delay was defined as time from initial examination in the ED to arrival at the Neurology Intensive Care Unit. RESULTS: The median interval of prehospital and emergency delays were 92.66 and 53 min, respectively. The major cause of the prehospital delay was the time from symptom onset to first call for medical help (68.21 min, 73.93%, beta coefficients: 0.99; p < 0.001), and the major cause of the ED delay was waiting for the neurological consultation (21.28 min, 39.6%), beta coefficients: 0.03; p < 0.001). CONCLUSION: The results indicate that prehospital and ED delays are due to late decision to seek medical care and delayed neurological consultation. Hence, educational campaigns are needed to increase public awareness of stroke signs and the necessity of calling emergency services immediately when persons are suffering a possible stroke. Equally, ED physicians need to be trained in the recognition of symptoms and signs of acute stroke and the necessity for rapid neurological evaluation.
