Objective: The results of single clamp and partial clamp techniques were retrospectively compared in elderly patients (> 70 years) undergoing coronary artery bypass grafting operation (CABG). Methods: A total of 244 elderly patients undergoing CABG between January 1995 and March 2002 in our center were studied. Single-clamp technique was used in 32 cases (Group 1) and partial-clamp technique was used in 212 cases (Group 2). All patients had isolated coronary artery lesions and a primary elective coronary bypass grafting surgery was planned for every case. Preoperative, operative and postoperative variables; age, gender, pre- and post-operative neurological status (stroke, amaurosis fugax, aphasia, hemiplegia, hemiparesis), cerebrovascular diseases, diabetes mellitus, hypertension, number of distal grafts, left ventricular score, durations of aortic cross-clamping and cardiopulmonary bypass (CPB) times, perfusion pressure during CPB, and postoperative cardiac status were recorded. Patients with a history of neurological complications were excluded from the study. Results: Overall, mean age was 71.9 ± 2.18. Patients in Group 1 were significantly older as compared to patients in Group 2 (p < 0.01). Average duration of cross-clamping in Group 1 was significantly longer (p<0.001) compared to Group 2, but there were no differences with regard to the total duration of cardiopulmonary bypass (p = 0.535). No patients had neurological complications in Group 1, however 22 patients in Group 2 had neurological complications (p £ 0.05). Conclusions: Although single-clamp technique was associated with a longer cross-clamp time, the duration of CPB was not increased and the incidence of neurological complications was low.

PMID: 14675877  Pages 299 - 302
Objective: To study immunohistochemical and electron-microscopic features of secretory cardiomyocytes in experimental myocardial infarction (MI). Methods: Totally 15 hearts of dogs with experimental MI were studied. For electron-microscopic study materials were collected from left atrium, and its several parts (appendix, lateral and frontal walls). For immunohistochemical analysis of atrial natriuretic factor (ANF) incubation in monoclone immune serum was used (standard monoclonal serum and primary mice antibodies, Immunon). For statistic processing we used Chi-square test (criterion of Pearson agreement). Results: Immunohistochemical and electron-microscopic investigation after 24 hours from experimental myocardial infarction indicated increase of specific activity of secretory cardiomyocytes and after 48 hours decrease of secretion of ANF while cardiomyopathy appears. After 72 hours, blockade of ANF secretion with decompensation of secretory cardiomyocytes occurred. Conclusion: Imunohistochemical investigations and analysis of submicroscopic structures of secretory cardiomyocytes after experimental MI showed, that cells were functionally active 24 hours after myocardial infarction with further (48 hours and 72 hours of MI) decrease in amount and impairement of activity.

Objective: Trimetazidine (TMZ) is a cellular anti-ischemic agent, which has been studied in clinical and experimental investigations, and was shown to have protective affects against myocardial ischemia and reperfusion injury. The major objective of this study was to investigate the cardio-protective effects of trimetazidine in prolonged global ischemia subjected Langendorff perfused rat hearts. Methods: Twenty rats (Male Sprague-Dawley) were divided into two study groups. In Group 2 (n=10) TMZ was given by intra-gastric gavage (3 mg/kg BW twice daily for 5 days) prior to operation and was added to the Krebbs-Henseleit perfusate to create a 10-6 M solution to perfuse the isolated rat hearts. Group 1 (n=10) reserved as control group and received saline at the same time period. All hearts were paced at 300 beats/min. After a 20-minute of stabilization period, hearts in both groups were arrested for 120 minutes with crystalloid cardioplegia. After ischemic period, the hearts were then reperfused for 30 minutes. Hemodynamic measurements from left ventricular latex balloon, coronary flow, and creatine kinase (CK-MB) and troponin T (cTnT) levels determined from the coronary effluent were analyzed at the end of stabilization and at every 10-min intervals during reperfusion, and results were compared between two groups. Results: No significant differences were observed in all entered hemodynamic and biochemical parameters between two groups at the end of the stabilization. However, peak systolic pressure, end diastolic pressure and +dP/dt values reflected improved mechanical myocardial recovery in Group 2 hearts after prolonged ischemia. Besides coronary flow measurements were higher in Group 2 compared with Group 1. CK-MB and cTnT levels indicated to less enzymatic damage in trimetazidine treated hearts during reperfusion. Conclusion: In conclusion, both pre-treatment and treatment protocols with TMZ reduce the myocardial damage caused by global ischemia following reperfusion. We could speculate that this beneficial effe

Objective: Sinus venosus type atrial septal defects (SVASD) differ from the secundum atrial septal defects by its location and high incidence of combination with other cardiac anomalies, which inherently increases the risk of postoperative complications. Right atriotomy is the most preferred approach for repairing the SVASD. Postoperative sinus node dysfunction or other rhythm disturbances can be observed. We compared the postoperative complications between lateral cavatomy and right atriotomy in patients who had SVASD. Methods: Twenty-seven patients who had SVASD (of 384 total ASD’s) associated with partial anomalous pulmonary venous connection (PAPVC) underwent surgical repair during the period of January 1992 – December 2001 in Gülhane Military Medical Academy. Sinus venosus type atrial septal defect was repaired through right atrial incision by routine bi-caval cannulation in 14 patients (Group 1) and repaired through lateral caval incision by direct caval cannulation in 13 patients (Group 2). Lateral cavatomy was closed by pericardial patch in Group 2. We analyzed the relationship between incidence of rhythm disturbances and the technique in patients who had SVASD with or without partial anomalous pulmonary venous connection prospectively. Results: All patients had a classical superior SVASD intraoperatively. Persistent left superior vena cava (PLSVC) was observed in 5 patients (Group 1=3 patients, Group 2=2 patients). Postoperative mortality was seen in one patient in Group 1 due to pulmonary venous obstruction. In Group 1, one patient underwent re-operation for upper and middle lobectomy of the right lung. Ambulatory Holter monitorizations were done in all patients per 3 months periodically. In Group 1 sinus node dysfunction was observed in 4 patients and atrial fibrillation was observed in 2 patients, while in Group 2 only one patient had atrial fibrillation during follow-up period (p=0.037). Conclusion: Repair of SVASD in adult patients is associated with low operative mortality and morbidity. The closure of the defect by pericardial patch is the most preferred technique but obstruction of caval veins can be seen. We suggest that posterior cavatomy can be preferred to atriotomy because of low incidence of sinus node dysfunction and pulmonary or caval obstruction.

Objective: It is well known that long-term therapy with beta-blockers reduces morbidity and mortality, improves left ventricular function in patients with heart failure. However the effect of beta-blockade on exercise tolerance in patients with heart failure remains unclear. In the present study we evaluated effects of the addition of bisoprolol to standart therapy with a diuretic and an angiotensin converting enzyme (ACE) inhibitor on exercise capacity in patients with chronic heart failure. Methods: We enrolled 52 patients (mean age 59±11 years) with stable, mild to moderate chronic heart failure and left ventricular ejection fraction of %40 or less receiving standart therapy with diuretic and ACE inhibitor. We randomly assigned patients to bisoprolol 1.25 mg (n=28) or control (n=24) groups. The drug progressively increased to a maximum dose of 5 mg per day. Cardiopulmonary exercise testing (CPET) was performed in all patients of the bisoprolol and control groups before and after 3 months from the beginning of the study. Results: We found a significant increase in exercise duration, maximal O2 uptake (pik VO2 ), the O2 uptake at the anaerobic threshold (VO2-AT) and O2-pulse (pik VO2/ HR), and improved functional capacity (p<0.001). Bisoprolol produced significant reduction in heart rate at rest (p=0.01) and during maximal exercise (p=0.041). In the control group no significant changes were observed. Conclusion: The addition of bisoprolol to the standart therapy in patients with mild to moderate heart failure is well tolerated and improves functional capacity.

Objective: When mitral stenosis is associated with other valve lesions, diagnosis, prognosis and the treatment strategies are affected. Mitral valve prolapse may occur in some patological settings that affect mitral apparatus. We investigated the incidence of valve lesions including mitral valve prolapse that accompany mitral stenosis and assessed the relation between echocardiographic measures. Methods: Two hundred and one patients (31 male, 170 female) between 16 and 72 years of age (mean age 40.9±11.4 years) with mitral stenosis were included in the study. Patients were divided into three groups according to the mitral valve area obtained by echocardiography using planimetric method as Group I (MVA<1.1 cm2), Group II (MVA 1.1-1.5 cm2) and Group III (MVA > 1.5 cm2). Results: Mitral stenosis with mitral regurgitation, aortic regurgitation, aortic stenosis, combined aortic valve disease, tricuspid regurgitaion and tricuspid stenosis were found in 117 (58.2%), 84 (41.8%), 18 (9%), 9 (4.5%), 62 (30.8%) and 6 (3%) patients, respectively. Twenty- three patients (11.4%) had mitral valve prolapse in only anterior leaflet. Nobody of patients had mitral valve prolapse of posterior mitral valve leaflet. Age, gender, rhythm, degree of stenosis, degree of mitral and aortic regurgitations, mean pressure gradient, left atrial diameter, ejection fraction and valve score did not differ in patients with and without mitral valve prolapse. Conclusion: Our study has shown that valve lesions including mitral valve prolapse frequently accompany mitral stenosis and the incidence of mitral valve prolapse in patients with mitral stenosis is high.

Objective: Endothelium-dependent vasodilatation is impaired in hypertension. Statins have been shown to improve endothelial functions in hyperlipidemic subjects. We aimed to investigate the effect of statins on endothelium-dependent flow mediated dilatation (FMD) and blood pressure (BP) in normocholesterolemic hypertensive patients. Methods: This randomized prospective study consisted of 56 patients with newly diagnosed essential hypertension. All patients received angiotensin converting enzyme (ACE) inhibitor lisinopril (5 mg/day) as antihypertensive therapy, and half of them were randomized to simvastatin(20mg/day) irrespective of serum lipid levels. All subjects underwent brachial artery ultrasonographic examination for the measurement of FMD before randomization and at the end of 12 weeks treatment. Results: A total of 39 patients completed the study (21 patients in the statin + ACE inhibitor group, and 18 patients in the ACE-inhibitor alone group). Blood pressure levels were substantially reduced in both groups after treatment. In statin+ ACE-inhibitor group systolic pressure reduced by 23% (p=0.0001) and diastolic BP reduced by 23% (p=0.0001). In ACE-inhibitor alone group these ratios were 20% (p=0.001) and 21% (p=0.001), respectively. Meanwhile, pulse pressure (PP) decreased by 25% in statin+ ACE-inhibitor group (P=0.0001) and by 16% in ACE inhibitor-alone group (p=0.0051). Baseline FMD was significantly impaired in overall patients with hypertension as compared with healthy controls (13 ± 8 vs. 24±8 %, P = 0.001). After treatment FMD decreased by 23% in lisinopril alone group (p=0.054). There were no correlations between FMD improvement, LDL reduction, BP or PP changes in both groups. Conclusion: Addition of simvastatin to ACE-inhibitor treatment in newly diagnosed hypertensive patients with normal cholesterol levels, significantly reduced PP and facilitated BP control, but did not affect endothelium-dependent dilatation. Further long-term large scale studies are needed to clarify the effect of various statins on endothelial functions of either hypercholesterolemic or normocholesterolemic hypertensive patients.

PMID: 14675886  Pages 340 - 347
Today, congestive heart failure and acute myocardial infarction, which is accepted as the main factor that contributes to the development of heart failure, are major causes of deaths despite advances in surgical procedures, mechanical assistance devices, drug therapy and organ transplantation. However, these procedures only prevent further myocardial deterioration and do not act on the underlying pathophysiology which are fibrosis and cardiac remodeling. As further advances in genetics provide the possibility of preventing fibrosis and cardiomyocyte regeneration in damaged myocardium, studies are being made in this way. For this reason, a variety of cell types including stem cells were used and successful results were obtained. After studies on animal models; pilot studies to explore the effect of cellular cardiomyoplasty and stem cell implantation on humans have been started. Data that have been gained from human studies till now are encouraging for further studies in this era. But there is a need for larger-scale randomized trials to determine the post-transplantation risk, as well as long-term safety and efficacy.
