Elisaf; Do statins have an antiarrhythmic activity? Moreover, atrial fibrillation is the most common arrhythmia encountered in the clinical practice.
The beneficial effect is zocor the same as simvastatin qt statins on cardiovascular morbidity and mortality is well-established, while the exact role of this class of /is-hydrochlorothiazide-safe-7-days.html against arrhythmias remains unclear.
This review discusses the effect of statin treatment on arrhythmias that are commonly seen in the clinical setting. The underlying pathophysiological mechanisms are also overviewed.
Compelling is zocor the same as simvastatin qt from the majority of the studies reviewed shows that statins exhibit a protective effect against the occurrence of ventricular arrhythmias and atrial fibrillation. Ventricular arrhythmias VA [i. Moreover, atrial fibrillation AF is the most common arrhythmia encountered in clinical practice, accounting for approximately one third of hospitalizations for cardiac rhythm disturbances [3]. An estimated of 2. There is evidence suggesting that hypertension, diabetes mellitus, /bad-effects-of-prilosec.html and simvastatin metabolic syndrome may be risk factors for AF [4].
Thus, AF, same simvastatin in older and hypertensive patients, might be part of the atherosclerosis spectrum [4]. Statins are the cornerstone in the management of dyslipidemia [5].
Clinical trials demonstrated that statin therapy is associated with a significant reduction in cardiovascular morbidity and mortality when used for either the primary or more info secondary prevention [6—9]. These favorable results are not entirely explained by lipid modulation itself [6]. Besides their lipid-lowering capacity, statins exhibit a variety of same simvastatin anti-atherogenic anti-inflammatory, anti-proliferative, anti-oxidative and anticoagulation actions [10—14].
Large randomized trials suggested that statin therapy may result in a sudden cardiac death reduction in zocor the with CAD [6,8].
This led to the hypothesis that part of the mortality benefit may lay beyond the anti-atherogenic effects of statins on coronary arteries and could be related to potential antiarrhythmic properties of such drugs against VA [15,16]. Moreover, despite the well-known anti-atherogenic actions, it is not simvastatin whether statins exhibit an antiarrhythmic is zocor the same as simvastatin qt against AF. In this review we discuss the effect of statin is zocor the same as simvastatin qt on the incidence of the most /slimex-15-x-48.html arrhythmias as well as simvastatin conditions that predispose to the development of these arrhythmias.
Furthermore, a manual search of major randomized clinical trials /diovan-similar-drugs-you-should-try.html statins was conducted. Additionally, the reference lists from simvastatin papers and review articles as well as major randomized clinical trials with statins were scrutinized. We included articles that were relevant to /jiva-brahmi-tablets-review-target.html topic of the same review.
Sudden cardiac death can be caused by VA due to acute myocardial ischemia or re-entrant arrhythmias /nootropil-1200-price-60x.html the setting of myocardial scar tissue [17]. In simvastatin presence of scar tissue, episodes is zocor the same as simvastatin qt myocardial ischemia and changes in autonomic tone can create conditions that make the recurrence of VA possible [18,19].
Clinical and autopsy studies have shown an association between elevated cholesterol levels and article source cardiac death [20]although a recent study showed that patients with acute myocardial infarction and primary ventricular fibrillation had less hypercholesterolemia compared to matched myocardial see more patients that did not exhibit primary ventricular fibrillation [21].
It has been postulated that statins have lipid-independent effects that could simvastatin regulate circumstances that are responsible for the development of VA in patients with CAD Fig. Specifically, statins are known to prevent progression or even promote regression of atherosclerotic plaques [22,23].
Furthermore, the anti-inflammatory and anti-proliferative effects of statins are well-established [11,12,24]. Additionally, statins may have beneficial effects simvastatin the coronary arterial tone by regulating the nitric oxide NO is zocor the same as simvastatin qt endothelial function through a statin-induced increase in the endothelial Is zocor the same as simvastatin qt production and bioavailability [13,14].
Moreover, statins may contribute significantly to the plaque stabilization in high-risk atherosclerotic lesions by modifying their lipid content [10,25].
These effects improve myocardial perfusion, ameliorate myocardial ischemia-reperfusion injury during an acute coronary syndrome [26] and reduce the risk is zocor the same as simvastatin qt plaque rupture, thereby preventing the ischemia-induced electrophysiological effects that predispose to VA [27].
Moreover, statin therapy may affect ventricular conduction and excitability by modulating the fatty acid composition and physiochemical properties of the sarcolemma that result in alterations in transmembrane ion channel properties [28]. It is also zocor the that statin administration may reduce ischemia-induced oxidative stress that leads to sarcoplasmic injury and intracellular calcium overload, conditions known to contribute to the development of VA [29].
Possible mechanisms of antiarrhythmic effects of statins. A Against ventricular arrhythmias. B Against atrial fibrillation. There are certain electrophysiological conditions recognized to predispose to VA.
Same simvastatin, decreased heart rate variability is zocor with decreased parasympathetic tone and has been shown to be a good predictor of arrhythmic events and sudden cardiac death [30,31]. Statins are suggested to have beneficial effects on heart rate variability. Specifically, Pehlivanidis et al. Of note, this was a small not randomized and not placebo-controlled study.
Similar results were obtained in patients with heart failure following atorvastatin treatment [33] also see below. There are also experimental data to support the clinical study results.
click Specifically, rosuvastatin increased heart rate variability in an animal model prone to atherosclerosis [34]. This increase was correlated with a statin-induced NO-dependent improvement in endothelial function [34].
