Background: Acute coronary syndrome is one of the most frequent indications for hospitalization. Acute intervention has been increasingly emphasized during the last decade. Norwegian local hospitals have few follow-up data for this condition.
Material And Methods: A cohort from a local hospital with a catchment area of 100,000 inhabitants was studied retrospectively and followed-up prospectively. Journals and ECG results were reviewed for all patients who were admitted locally or referred to PCI with the diagnosis acute coronary syndrome. The patients were classified as having either myocardial infarction with ST-elevation (STEMI), myocardial infarction without ST-elevation (NSTEMI), or unstable angina pectoris (UAP). Surviving patients were contacted for 6-month follow-up data.
Results: 206 patients with acute coronary syndrome were included (37% women). There were 43 patients (22%) with STEMI, 127 (62%) with NSTEMI and 32 (17%) with UAP. The mean age for onset of myocardial infarction was 67 years in the STEMI group and 76 years in the NSTEMI group. Six months mortality rate for the entire group was 17.5%, and rates for the subgroups were STEMI (14%), NSTEMI (23%) and UAP (3%). There were no deaths in the 15 patients with STEMI who underwent primary PCI < 12 hours after onset.
Interpretation: Mortality in acute coronary syndrome was higher in our study than for that reported in randomized trials, but comparable to recent reports on mortality in patients with NSTEMI.

Cachectic biomarkers as confounders behind the obesity paradox in patients with acute decompensated heart failure.
Int J Obes (Lond)

Department of Cardiology, Sakakibara Heart Institute, Tokyo, Japan.
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).

Section of Interventional Cardiology, MedStar Washington Hospital Center, Washington, DC, USA. Electronic address:
Background: The benefit of mechanical circulatory support (MCS) with Impella (Abiomed, Inc, Danvers, MA) for patients undergoing non-emergent, high-risk percutaneous coronary intervention (HR-PCI) is unclear and currently the subject of a large randomized clinical trial (RCT), PROTECT IV. While contemporary registry data from PROTECT III demonstrated improvement of outcomes with Impella when compared with historical data (PROTECT II), there is lack of direct comparison to the HR-PCI cohort that did not receive Impella support.
Methods: We retrospectively identified patients from our institution meeting PROTECT III inclusion criteria (left ventricular ejection fraction [LVEF] <35% with unprotected left main or last remaining vessel or LVEF <30% undergoing multivessel PCI), and compared this group (NonIMP) to the published outcomes data from the PROTECT III registry (IMP).
