BACKGROUND: Cardiovascular disease is the first cause of death globally with myocardial infarction as the main event. Heart rate variability (HRV) has been associated with an increased risk of mortality post-myocardial infarction. However, which indices of heart rate variability are the best predictors for total and cardiac mortality post-myocardial infarction remains unclear. We performed a systematic review to evaluate this association. METHODS AND RESULTS: PubMed, Google Scholar, Embase and Cochrane databases were searched for studies with HRV as a predictive mortality marker...

UNLABELLED: The patient, a 68-year-old man, presented to our emergency room with chest pain, prompting an emergency cardiac catheterization due to elevated cardiac troponin-I levels. While no obvious coronary artery stenosis was found, there was evidence of apical ballooning wall motion in the left ventricle, leading to a diagnosis of takotsubo syndrome. Three months later, he occasionally experienced chest pain at rest, prompting us to conduct another cardiac catheterization. Left ventriculography showed normal contraction...

Diastolic dysfunction (DD) in heart failure (HF) is associated with increased myocardial cytosolic calcium, and calcium-efflux via the sodium-calcium-exchanger depends on the sodium gradient. Beta-3-adrenoceptor (β3-AR) agonists lower cytosolic sodium and have reversed organ congestion. Accordingly, β3-AR agonists might improve diastolic function, which we aimed to assess. In a first-in-man, randomized, double-blinded trial, we assigned 70 patients with HF with reduced ejection fraction (HFrEF), NYHA II-III, and LVEF<40% to receive the β3-AR agonist mirabegron (300 mg/day) or placebo for six months, in addition to recommended HF therapy...

Introduction To predict postoperative myocardial infarction rates in patients who undergo noncardiac surgery, the Canadian Cardiovascular Society Guidelines on Perioperative Cardiac Risk Assessment and Management recommends assessment of brain natriuretic peptide (BNP) in certain patients. Serial troponins are measured if the BNP level is elevated. In certain cases, Revised Cardiac Risk Index (RCRI) alone does not perform well, for example, during vascular surgery. Cardiac events occur in 20% of all vascular surgery patients...
