Purpose Of Review: To provide updates regarding the optimal duration of dual antiplatelet therapy (DAPT) in patients with acute coronary syndromes (ACS).

Recent Findings: Within the past years, five moderate-sized randomized controlled trials evaluated different DAPT durations after percutaneous coronary intervention. These studies included a significant percentage of ACS patients that varied from 30 to 75% depending on the study. Results suggest that in selected populations prolonging DAPT does not offer additional protection from ischemic events and increases bleeding complications. However, results from a large-scale registry illustrate that DAPT durations beyond 6 months are associated with lower cardiovascular risk. Moreover, a multicenter registry demonstrated that the context underlying DAPT cessation is an additional correlate of outcomes after stent implantation.

Summary: Current guidelines suggest 12 months of DAPT after an initial presentation with ACS. Emerging evidence suggest that in selected populations shorter duration might be acceptable.

Empagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, has garnered significant interest due to its potential cardiovascular benefits, particularly in patients experiencing acute myocardial infarction (AMI) who are undergoing primary percutaneous coronary intervention (PCI). This systematic review aims to evaluate the effectiveness of Empagliflozin in improving clinical outcomes in this patient population. A systematic review of randomized controlled trials (RCTs) was conducted to assess the effects of Empagliflozin on clinical outcomes in patients with AMI undergoing primary PCI.

Frequent changes in altitude and oxygen levels limit the practical application of traditionally derived exercise thresholds or training zones based on heart rate (HR) or blood lactate concentration (bLa). We investigated the transferability of a muscle oxygenation (SmO)-based intensity prescription between different hypoxic conditions to assess the suitability of real-time SmO measurements for ski-mountaineering (SKIMO) athletes during submaximal endurance exercise. A group of 15 well-trained male SKIMO athletes performed a graded-intensity run test in normoxia (87 m ASL, FiO = 20.

Vitamin D deficiency is one of the most common metabolic disorders in the European population. A low level of 25-OH vitamin D3 is related to an elevated risk of myocardial infarction (MI). The aim of our study was to examine the relationship between calcidiol and calcitriol serum concentration and left ventricular ejection fraction early after interventional treatment for acute coronary syndrome.
