Relationship between anti-hypertensive drugs and LVH regression and reported % reductions of the left ventricular mass, while the use of ACE inhibitors. Left ventricular hypertrophy associated with chronic cocaine abuse. were enrolled in an inpatient drug rehabilitation program were considered for the study .

In particular, ACE inhibitors have shown promising cardio-protective effects in experimental models of hypertensive heart disease;22 specifically, these inhibitors improve micro-vascular ischemia, ventricular function and arrhythmias. Conversely, the occurrence of these events increased when cardiac hypertrophy increased or remained stable.

Treatments consisted of medication and lifestyle changes. For individuals who showed an improvement in LVH, the rate of cardiovascular events was 1. In the groups that experienced no change or a worsening in LVH, the rate of cardiovascular events was 6.

These researchers also noted that this association did not depend on the initial ventricular mass, clinical parameters or monitored baseline blood pressure. Their final conclusion was that for primary hypertension, the decrease in ventricular mass during treatment is a favorable prognostic marker for subsequent morbid events. Relationship between anti-hypertensive drugs and LVH regression With the exception of minoxidil and hydralazine, which are peripheral vasodilators, the other anti-hypertensive drugs provided full or partial LVH regression.

In the literature, there are few monotherapy treatment meta-analyses. In addition, different groups report contradictory results. The difference between different anti-hypertensive drugs regarding their ability to reverse LVH may be determined by neural and humoral factors. The findings of these three studies conflict with the findings of some previous meta-analyses, and as such, these researchers have suggested that the effects of anti-hypertensive drug must be evaluated individually on their important intermediate targets, such as LVH, with appropriate patient populations.

The extrapolation of the LVH regression effects based on the anti-hypertensive drug classification may lead to clinical mistakes and needs to be carefully reconsidered. For instance, our group investigated isoproterenol-induced LVH in albino rats, which typically leads to hypertrophy without an increase in the after-load, and reported LVH regression by gavage administration of enalapril15, 16, 28, 31 and verapamil.

Alpha-methyldopa, captopril, beta-blockers and calcium channel blockers promote the regression of hypertrophy, while other drugs, such as hydralazine and minoxidil, reduce blood pressure without influencing ventricular hypertrophy. The ratio of ventricular mass to pressure is often weak, even in relation to blood pressure monitored every 24 hours.

Anti-hypertensive drugs have different effects on ventricular hypertrophy regression

Intrinsic properties of anti-hypertensives on LVH regression: A decrease in cardiac mass may not depend only on daily arterial pressure measurement. They evaluated the genetic association of the Sokolow-Lyon voltage index and the Cornell product index, the septal thickness and the ventricular wall, ventricular dimensions and left ventricular mass in members of British households, all items were evaluated n pairs and together.

Chromosomes 10, 12 and 17 were the genetic loci involved and had the most important influence on LVH, as detected by the electrocardiogram. However, the quantitative differences in LVH, known as phenotypes, may also be the result of individual differences besides those produced by the various anti-hypertensive drugs i.

Current medical literature shows the direct relationship between LVH and mortality, as well as the relationship between LVH regression and decreasing mortality. The literature also provides evidence for hypertrophic variations in response to the effect of different anti-hypertensive drugs and differences in the hemodynamic patterns.
