Acute coronary syndrome (ACS) during pregnancy is rare but may be associated with high risk complications. Approximately 150 myocardial infarctions (MI) during pregnancy have been documented in literature worldwide, but we didn't find one with myocardial aneurysm. We describe 2 patients with acute MI; both with ST segment elevation (STEMI), 1 case complicated with heart failure, formation of a myocardial aneurysm and broad QRS arrhythmia; another with uncomplicated course, and their anesthetic management during delivery. Acute MI is rare in reproductive age usually developing in women with cardiovascular risk factors. There is concern about its rising incidence due to the increase of average maternal age. Our cases show that there might be some undiscovered risk factors for pregnancy related myocardial infarction.

Postinfarction ventricular septal rupture (PIVSR) is a rare but serious complication of acute myocardial infarction. Determining how to conduct surgical repair safely is critical. We compared the outcomes of Impella and intra-aortic balloon pump (IABP) implantation during perioperative mechanical circulatory support management in patients with PIVSR (n = 22).

Background: Obesity is a risk factor for heart failure (HF) development but is associated with a lower incidence of mortality in HF patients. This obesity paradox may be confounded by unrecognized comorbidities, including cachexia.
Methods: A retrospective assessment was conducted using data from a prospectively recruiting multicenter registry, which included consecutive acute heart failure patients.

HFpEF is a prevalent and complex type of heart failure. The concurrent presence of conditions such as obesity, hypertension, hyperglycemia, and hyperlipidemia significantly increase the risk of developing HFpEF. Mitochondria, often referred to as the powerhouses of the cell, are crucial in maintaining cellular functions, including ATP production, intracellular Ca regulation, reactive oxygen species generation and clearance, and the regulation of apoptosis.

Pulmonary vascular diseases, particularly when accompanied by pulmonary hypertension, are complex disorders often requiring multimodal imaging for diagnosis and monitoring. Echocardiography is the primary screening tool for pulmonary hypertension, while cardiac MR imaging (CMR) is used for more detailed characterization and risk stratification in right ventricular failure. Chest computed tomography (CT) is used to detect vascular anomalies and parenchymal lung diseases.

Objective: Frailty has become an increasingly recognized perioperative risk stratification tool. While frailty has been strongly correlated with worsening surgical outcomes, the individual determinants of frailty have rarely been investigated in the setting of aortic disease. The aim of this study was to examine the determinants of an 11-factor modified frailty index (mFI-11) on mortality and postoperative complications in patients undergoing endovascular aortic aneurysm repair (EVAR).
