Left ventricular hypertrophy (LVH) is a frequent and well-recognized consequence of a chronically elevated blood pressure (BP). Several studies have demonstrated that LVH is an independent cardiovascular risk factor, associated with an increased likelihood to develop cardiovascular complications such as congestive heart failure, sudden cardiac death, coronary heart disease and stroke [1,2]. Conversely, an aggressive treatment of hypertension can prevent and reverse LVH and reduce the incidence of cardiovascular events [3,4].
Non-haemodynamic factors leading to LVH
If BP is definitively the major trigger for the development of cardiac hypertrophy in hypertension, left ventricular mass may be affected by several other non-haemodynamic factors which may also play an important role in the pathophysiology of LVH, as listed in Table 1. Factors such as gender, age, race, obesity, alcohol consumption, catecholamines, ANP, aldosterone and angiotensin II and genetic factors (polymorphism of ACE) have all been considered as BP-independent
Does sodium have a role in the development of LVH?
What is the normal BP in mice with cardiac hypertrophy?
