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-...

The relation between dyspnoea of presumed cardiac origin and disturbed left ventricular systolic function was studied in a group of 67 year old men from the general population of Gothenburg, Sweden. Forty two men with cardiac dyspnoea were identified and 45 controls were randomly selected from a screened cohort of 644 men. Dyspnoea was graded according to the World Health Organisation standard,...

The traditional approach to the ECG diagnosis of left ventricular hypertrophy (LVH) is focused on the best estimation of left ventricular mass (LVM) i.e. finding ECG criteria that agree with LVM as detected by imaging. However, it has been consistently reported that the magnitude of agreement is rather low as reflected in the low sensitivity of ECG criteria. As a result, the majority of cases w...

Introduction: Psoriasis is a chronic inflammatory skin disease characterized by plaques covered with silvery scales. Psoriasis is highly prevalent in different countries in the world, including Iran. Several studies have reported a significant association between psoriasis and cardiovascular diseases. This study aimed to evaluate the relationship between psoriasis and cardiac disease using echo...

BACKGROUND Obesity is a chronic and multifactorial disease, associated with increased cardiovascular risk, especially diastolic heart failure. OBJECTIVE To evaluate left ventricular diastolic function in morbidly obese patients in the pre-operative for bariatric surgery, correlating it with cardiovascular risk factors and heart structure. METHODS This is a cross-sectional study with 132 pat...

AIM To determine the direct effect of obesity on echocardiographic indices of diastolic left ventricular function METHODS 44 obese (BMI > or =25 kg/m2) and 45 normal weight women were studied. They had no other pathological conditions. Echocardiographic indices of diastolic function were obtained, and dysfunction was assumed when at least two values differed by > or =2 SD from the normal weig...
