Androgenic steroids dysregulation and the risk of coronary artery disease.

INTRODUCTION: Endogenous testosterone deficiency or excess anabolic-androgenic steroids (AAS) have been linked to alter the physiology of different organs in the body, more specifically, the vasculature of coronary arteries. Despite the health-related concerns of using synthetic testosterone derivatives, such as AAS, there has been a tremendous increase in the use of AAS among athletes and bodybuilders. AREAS COVERED: We have highlighted the three main mechanisms that AAS increase the risk of coronary artery disease (CAD): altering the homeostasis of lipid metabolism which results in dyslipidemia and subsequently atherosclerosis, disturbing the function of platelet which results in platelet aggregation and subsequent thrombosis, and increasing the risk of coronary vasospasm by affecting the physiological function of vascular bed. EXPERT OPINION: Despite the restriction of AAS in specific clinical conditions such as testosterone deficiency and cancer therapy, many amateurs' athletes misuse the AAS. Although there has been a strong association between the AAS misuse and risk of developing CAD, the more valued approach would be a randomized clinical double-blind trial. The suggested primary endpoint would be an occurrence of adverse cardiovascular events, such as myocardial infarction, cerebrovascular accidents, and death. Increasing awareness of the risk of missing AAS among high-risk groups is imperative.

Efficacy and Safety of Transcarotid Transcatheter Aortic Valve Replacement: A Systematic Review.

BACKGROUND: In patients who are not suitable for traditional access routes for transcatheter aortic valve replacement (TAVR) due to severe peripheral vascular disease (PVD) or prohibitive surgical risk, carotid artery (CA) access is an emerging route for TAVR. This study represents the most up to date on outcomes of carotid access TAVR. METHODS: A systematic review was conducted as per the Preferred Reporting Instructions for Systematic Reviews and Meta-analysis (PRISMA). We performed a thorough electronic search through Pubmed, SCOPUS and Embase databases. Statistical analyses were performed using SPSS version 24 (IBM Corporation, Armonk, New York, USA). RESULTS: A total of 15 non-randomized studies were included in this systematic review comprising of patients that received TAVR via 4 vascular access sites, transcarotid (TC) (N = 1035), transfemoral (TF) (N = 1116), transapical (TAP) (N = 307), transaortic (TAO) (N = 176) and transaxillary (TAX) (N = 90). In the Transcarotid cases, device success was achieved in 95.6% of patients (n = 748). The 30-day and 1-yr mortality was 4.2% and 10.5% respectively. 15.3% of patients required new pacemaker implantation. In-hospital stroke or TIA occurred in 4% of cases. 30-day stroke or TIA occurred in 5% of cases. There were no hemorrhagic strokes. 30-day Mortality was significantly higher in the Transaortic group (12.1%) compared to the Transcarotid group (2.6%) [RR = 2.93 95% CI = 1.15-7.58; p = 0.027]. There were no differences in outcomes between the Transcarotid group and the Transapical or Transaxillary groups. CONCLUSION: The most contemporary data on Carotid access TAVR shows impressive device success, low rates of stroke and pacemaker implantation and an acceptable 30-day and 1-year mortality. 30-day mortality was significantly lower in TC compared to TAO patients.

Managing hypertension in patients with heart failure: an ongoing quandary.

PURPOSE OF REVIEW: Hypertension (HTN) is one of the strongest risk factors for heart failure and is prevalent in up to 91% of patients with newly diagnosed heart failure. This article offers a practical approach to HTN in patients with heart failure. RECENT FINDINGS: To date, no randomized trials comparing specific antihypertensive regimens have been conducted in the heart failure population. Management of heart failure with reduced ejection fraction patients with elevated blood pressure (BP) should include guideline-directed medical therapy [angiotensin-converting-enzyme inhibitors (ACEis), aldosterone receptor blockers, AT1 neprilysin-inhibitors, beta blockers and aldosterone blockers] titrated to maximal tolerated doses regardless of BP. Despite the lack of survival benefit current available data suggest the use of ACEis, aldosterone receptor blockers as first-line therapy for HTN in patients with heart failure with preserved ejection fraction. SUMMARY: Management of HTN in heart failure patients should be based on left ventricular function. Recent findings suggest that AT1 neprilysin-inhibitors offer better BP control when compared with ACEi, or aldosterone receptor blockers and therefore should be used as first-line therapy in hypertensive patients with heart failure with reduced ejection fraction. Their role as antihypertensive agents in heart failure with preserved ejection fraction seems promising but remains under investigation.

Treatment of Concomitant OAB and BPH.

The etiology of men's lower urinary tract storage and voiding symptoms involves a contribution from both detrusor and outlet. As such, treatment of benign prostatic enlargement (BPE) ± benign prostatic obstruction (BPO) with standard alpha-adrenergic blockade and 5-alpha reductase inhibitor therapy may leave a population of men with persistent and bothersome urinary storage symptoms. An abundance of adequately powered, randomized, placebo-controlled trials indicate that the use of antimuscarinics and beta-3 adrenergic agonists, either alone or in combination with standard BPE/BPO therapy, leads to improvement in storage symptoms. At the same time, metrics associated with urinary emptying, such as maximum flow rate, post-void residual urinary volume, and incidence of treatment-associated urinary retention, appear to be stable and not significantly impacted by the addition of antimuscarinics.
