Detailed echocardiographic evaluation was performed on sixty-four normal persons without any cardiovascular risk factor and clinic blood pressure of 120/80 mm of Hg or less with an aim to find, if there are subclinical echocardiographic changes even in this population. There was significant positive linear correlation between mean arterial pressure and LV mass index. On dividing the patients ac...
Diabetes mellitus (DM) itself may induce subclinical myo-cardial dysfunction without significant coronary artery disease. Accordingly, adults with type 2 DM are susceptible for heart failure and a lot of experimental studies have shown significant changes in microvasculature and myocardial interstitial fibro-sis in type 2 DM. 2-4) Therefore, early recognition of subclinical myocardial dysfuncti...
BACKGROUND Subclinical left (LV) and right ventricular (RV) dysfunction has been demonstrated in type 2 diabetes mellitus and evidence indicates impaired LV diastolic function in type 1 diabetes mellitus (T1DM) as well. The aim of our study was to evaluate the role of tissue Doppler imaging (TDI) in assessment of global LV and RV function in T1DM patients. METHODS A detailed two-dimensional, ...
Background The prevalence of obesity is increasing worldwide. Obese children without hypertension are becoming an important health challenge. Aims Complications of obesity in adults are well established, but in obese children, cardiac dysfunction has not been reported clinically. Settings and Design The present crosssectional study investigates subclinical systolic and diastolic dysfunction...
AIMS It is unclear whether subclinical vascular damage adds significantly to Systemic Coronary Risk Evaluation (SCORE) risk stratification in healthy subjects. METHODS AND RESULTS In a population-based sample of 1968 subjects without cardiovascular disease or diabetes not receiving any cardiovascular, anti-diabetic, or lipid-lowering treatment, aged 41, 51, 61, or 71 years, we measured tradit...
BACKGROUND The dramatic increase in the prevalence of metabolic syndrome is associated with more increased cardiovascular morbidity and mortality in this group. Some recent studies suggested that metabolic syndrome is associated with increased risk of subclinical left ventricular (LV) systolic dysfunction. In the present cross-sectional case-control study, the utility of two-dimensional speckle...
AIMS We sought to determine the prevalence of overt and subclinical LV dysfunction in patients with critical left anterior descending coronary artery (LAD) stenosis but without a history of myocardial infarction and to compare diagnostic value of routine echocardiographic parameters with myocardial strain analysis for detection of critical LAD stenosis. METHODS AND RESULTS We retrospectively ...
Growing evidence suggests that thyroid dysfunction may contribute to progression of cardiac disease to heart failure. We investigated the effects of a therapeutic dose of thyroid hormones (TH) on cardiomyopathic (CM) hamsters from 4 to 6 mo of age. CM hamsters had subclinical hypothyroidism (normal thyroxine, elevated TSH). Left ventricular (LV) function was determined by echocardiography and h...
Current knowledge on the pathogenesis of diastolic heart failure predominantly rests on case-control studies involving symptomatic patients with preserved ejection fraction and relying on invasive diagnostic procedures including endomyocardial biopsy. Our objective was to gain insight in serum and urinary biomarkers reflecting collagen turnover and associated with asymptomatic diastolic LV dysf...
