| | Thus, the development of LVH is characterized by myocyte hypertrophy and by an imbalance between the myocytes and the interstitium of the myocardial skeletal structure. | | | Increased afterload secondary to hypertension leads to an increase in left ventricular wall tension and transmural pressure, compromising coronary blood flow during diastole. | | | Chronically elevated afterload and resulting LVH can adversely affect both the active early relaxation phase and late compliance phase of ventricular diastole. |

| | Left Ventricular Hypertrophy-Description |
| | Left ventricular hypertrophy (LVH) is a condition wherein the cardiac muscle responds to increased resistance in the circulation by becoming enlarged, much as you would expect any muscle to do when challenged by 'exercise'. | | | However, with time, the fibers of the hypertrophied heart muscle become thickened and shortened, and consequently less able to relax. | | | It becomes, thereafter, more difficult to relax and go through the normal cycle of contraction and relaxation. |

| | Left Ventricular Hypertrophy |
| | These changes are followed by an attenuation of the increase in cardiac output seen in the early phases of hypertension [66], with parallel development of vascular/cardiac hypertrophy and remodeling as well as increased arterial stiffness. | | | In support of this “integration” hypothesis, ambulatory blood pressures measured over a 24 hour period are more closely correlated with LV mass than blood pressure measurements obtained in a clinical setting [47, 61]. | | | Echocardiographic studies have enhanced our understanding of the etiology of hypertensive LV hypertrophy and dysfunction in epidemiologic studies over the past two decades. |
