The correlations between blood pressure, left ventricular hypertrophy and left atrial enlargement were examined in 2,010 autopsied cases. The cases were classified into 3 groups: 972 (48.2%) normotension cases, 313 cases (15.5%) of systolic hypertension and 725 cases (36.1%) of diastolic hypertension. The incidence of left ventricular hypertrophy (LVH) was significantly higher in systolic and d...

AIMS Left ventricular ejection fraction (EF) is a suboptimal measure of ventricular function. Recent mathematical modelling of left ventricular contraction has shown that the EF is determined by both myocardial shortening (strain) and by end-diastolic wall thickness. Increasing end-diastolic wall thickness resulted in augmented radial wall thickening. This may result in a significant 'overestim...

BACKGROUND The progression of pressure-overload left ventricular hypertrophy (LVH) to chronic heart failure (CHF) may involve a relative deficit in energy supply and/or delivery. METHODS AND RESULTS We measured myocardial creatine kinase (CK) metabolite concentrations and adenosine triphosphate (ATP) synthesis through CK, the primary energy reserve of the heart, to test the hypothesis that AT...

BACKGROUND Left ventricular hypertrophy (LVH) is an important risk factor for cardiovascular events, and its detection usually begins with an electrocardiogram (ECG). OBJECTIVE To evaluate the impact of complete left bundle branch block (CLBBB) in hypertensive patients in the diagnostic performance of LVH by ECG. METHODS A total of 2,240 hypertensive patients were studied. All of them were ...

Protein kinase C (PKC) activity and isozyme distribution were evaluated during development of pressure-overload-induced cardiac hypertrophy. Three-week-old rats were loosely banded on the ascending aorta (left ventricular hypertrophy [LVH] group). Two weeks later, when left ventricular mass was 50% greater than in the sham-operated control group and cardiac mass was still rapidly increasing bey...

Chronic treatment with suprapharmacologic doses of peroxisome proliferator-activated receptor (PPAR) agonists has a known potential for causing left ventricular hypertrophy (LVH). The mechanism by which LVH develops is not well understood nor are biomarkers of it well characterized. Natriuretic peptides are important regulators of cardiac growth, blood volume, and arterial pressure and may be u...

or massive RVH can the electromotive forces generated in the right ventricle (RV) counterbalance those produced in the left ventricle (LV).1 2 Our experience as well as that of several others-9 has demonstrated the usefulness and merits of the orthogonal vectorcardiogram. Furthermore, Toshima et al.'0 using the Schmitt-Simonson system (SVEC III) in patients with mitral and aortic valvular disea...

We compared the response of myocardial blood flow to exercise in normal dogs and in dogs with left ventricular hypertrophy (LVH) produced by banding the ascending aorta at 6-9 weeks of age. Blood flow was measured with 15-fim microspheres after the animals with LVH had reached adulthood when left ventricular:body weight ratios were approximately 80% greater than normal. During resting condition...

Left ventricular hypertrophy (LVH) was produced in guinea pigs after aortic stenosis (AS). The percentage of LVH in AS was determined by normalizing left ventricular (LV) weight by the mean LV weight of sham-operated controls (n = 12). After 3 weeks of cardiac overload, a mild LVH (30 +/- 3%) was induced in 17 animals and a relatively severe LVH (56 +/- 3%) was induced in 7 animals. LV papillar...
