Protective effect of left ventricular hypertrophy in right coronary artery occlusions
Abstract
The left ventricular function parameters of group A were better than those of group B: the ratio end-diastolic pressure/systolic pressure (EDP/SP) (A: 0.108±0.036; B: 0.121±0.050; p<0.05); the end-diastolic volume index (A: 75.9±31.3ml/m2; B: 88.0±31.0ml/m2; p<0.01); the end-systolic volume index (A: 16.0±10.0ml/m2; B: 27.0 ±20.0ml/m2; p<0.001); the ejection fraction (A 78.6±10.8%; B 67.7±17.9%; p<0.001); the anteroinferior shortening (A: 43.9±10.3%; B: 35.1±12.8%; p<0.001). A higher degree of ...

A higher degree of coronary tortuosity was observed in group A than in group B (78.2% and 24.1%; p<0.001) and also a more frequent absent or minimal diaphragmatic hypokinetic area (A: 80.8%; B: 54.0%; p<0.05). Conclusion - LVH reduces the effects of myocardial sequela and protects LV function when right coronary occlusion develops. ...
