Work-life conflict and cardiovascular health: 5-year follow-up of the Gutenberg Health Study.

PLoS One 2021 7;16(5):e0251260. Epub 2021 May 7.

Institute and Policlinic of Occupational and Social Medicine (IPAS), Faculty of Medicine Carl Gustav Carus, TU Dresden, Germany.

Introduction: Work-life conflicts (WLC) may impact health, but few studies prospectively consider the impact of WLC on objective outcomes such as cardiovascular disease. Using data from the Gutenberg Health Study (GHS), we examined if WLC at baseline was associated with an increased five-year incidence of cardiovascular events (myocardial infarct, stroke, atrial fibrillation, peripheral artery disease, coronary artery disease, chronic heart failure, sudden cardiac death). We also considered if WLC was associated with incident hypertension and arterial stiffness and if the effects of WLC on cardiovascular health differ for men and women. Read More

Colchicine and the heart.

Eur Heart J 2021 May 7. Epub 2021 May 7.

GenesisCare, 3/140 Mounts Bay Rd, Perth, Western Australia, Australia.

Colchicine is a unique, sophisticated anti-inflammatory agent that has been used for decades for the prevention of acute inflammatory flares in gout and familial Mediterranean fever. In recent years, clinical trials have demonstrated its potential in a range of cardiovascular (CV) conditions. Colchicine is avidly taken up by leucocytes, and its ability to bind to tubulin and interfere with microtubular function affects the expression of cytokines and interleukins, and the ability of neutrophils to marginate, ingress, aggregate, express superoxide, release neutrophil extracellular traps, and interact with platelets.

[50 years of electrophysiology and cardiac pacing].

G Ital Cardiol (Rome) 2021 May;22(5):341-351

U.O.C. Cardiologia, Ospedale G.B. Grassi, Ostia (RM).

During the last 50 years a continuous improvement was observed in the field of cardiac pacing and electrophysiology as for as both technological and clinical aspects were concerned. We moved from the first recording of the His bundle electrogram to the identification of the various mechanisms and sites of supraventricular and ventricular tachyarrhythmias, to three-dimensional mapping and ablation of different reentry circuits and eventually to pulmonary vein isolation for the treatment of atrial fibrillation. As far as cardiac pacing is concerned, we moved from single chamber to dual chamber pacing, to ventricular pacing and implantable automatic defibrillators provided by sophisticated diagnostic and therapeutic algorithms and by remote control.

The Role of Renin-Angiotensin-Aldosterone System in the Heart and Lung: Focus on COVID-19.

Front Pharmacol 2021 20;12:667254. Epub 2021 Apr 20.

Campania Regional Centre for Pharmacovigilance and Pharmacoepidemiology, Naples, Italy.

The renin-angiotensin-aldosterone system (RAAS) firstly considered as a cardiovascular circulating hormonal system, it is now accepted as a local tissue system that works synergistically or independently with the circulating one. Evidence states that tissue RAAS locally generates mediators with regulatory homeostatic functions, thus contributing, at some extent, to organ dysfunction or disease. Specifically, RAAS can be divided into the traditional RAAS pathway (or classic RAAS) mediated by angiotensin II (AII), and the non-classic RAAS pathway mediated by angiotensin 1-7. Read More
