The objective of this study was to assess the influence of left ventricular (LV) geometric pattern on coronary vasomotion in patients with essential hypertension. We studied 34 hypertensive patients, who had never been treated, with angiographically normal coronary arteries. Patients were classified into four LV geometric patterns by echocardiography: normal, concentric remodeling, eccentric hy...

background: early diagnosis of left ventricular mass (lvm) inappropriateness and left ventricular hypertrophy   (lvh) can result in preventing diastolic left ventricular dysfunction and its related morbidity and mortality. this study was performed to determine if diastolic dysfunction   is associated with lvh and inappropriate lvm. methods: one hundred   and twenty five uncomplicated hypertensi...

To evaluate the prognostic significance of clinicopathological measurement in the diagnosis of acute myocardial infarction (MI) in sheep, acute MI was induced by ligation of left anterior descending coronary artery (LAD). For this purpose, twenty four healthy sheep were divided into the sham-operated or control group (group I, thoracotomy without MI) and the experimental group (group II, with M...

Selective COX-2 inhibitors are most widely used analgesic and anti-inflammatory drugs;however, its maximal use is highly associated with various serious abnormal cardiovascularevents. Beraprost sodium (BPS), prostacyclin analogue has been shown to vasodilatory,antiplatelates, anti-inflmmatory, and antioxidant activity. The objective of the present study wasto evaluate the effect of BPS on celec...

Introduction: We aimed to investigate the effect of right bundle branch block (RBBB) on perfusion and functional parameters in dipyridamole stress/rest Tc99m-MIBI gated myocardial perfusion SPECT (GSPECT) which may be helpful in interpretation of myocardial perfusion imaging. Methods: We studied 73 patients with low pre-test likelihood of coronary artery disease in two groups:  38 patients wit...

Left ventricular (LV) relaxation was studied in patients with hypertrophic cardiomyopathy (HCM, n =18), congestive cardiomyopathy (CCM, n = 11), hypertensive heart disease (HHD, n = 8), coronary artery disease (CAD) without left ventricular (LV) asynergy (n = 9) and with LV asynergy (n =17), mitral stenosis (MS, n = 16), and mitral regurgitation (MR, n = 8). The time constant T and peak negativ...

background: left ventricular (lv) twist is due to oppositely directed apical and basal rotation and has been proposed as a sensitive marker of lv function. we sought to assess the impact of chronic pure mitral regurgitation (mr) on the torsional mechanics of the left human ventricle using tissue doppler imaging. methods: nineteen severe mr patients with a normal lv ejection fraction and 16 non-...

conclusions silent ventricular systolic dysfunction was more common in the patients with sle than in the control group. newer echocardiographic techniques such as two-dimensional ste provide an earlier chance for the detection of subclinical lv systolic dysfunction. our findings were independent of the traditional risk factors. results the mean duration of sle was 5.5 ± 3.4 years in our patient...

Background Left ventricular hypertrophy (LVH) is known to be associated with all-cause mortality and morbidity. There is a strong relationship between LV mass and afterload but the influence of aortic vasculopathy on ventricular geometry is less well understood. Aortic stiffness (AS) is one of the earliest detectable signs of the changes that alter the structure and function of the vessel wall,...
