AI Article Synopsis

  • The study investigates whether patients over 75 who experience ST elevation myocardial infarction (STEMI) treated with primary PCI have similar survival rates as their peers.
  • Researchers analyzed data from 450 patients and found that their survival rates at 1, 3, and 5 years were comparable to a matched reference population, with no significant impact from sex on survival outcomes.
  • Overall, the findings indicate that the critical phase for survival is within the first 30 days post-STEMI, after which the long-term survival rates for elderly patients align closely with those of the general population.

Article Abstract

Introduction: Mortality caused by ST elevation myocardial infarction (STEMI) has declined because of greater use of primary percutaneous coronary intervention (PCI). It is unknown if patients >75 have similar survival as peers. We aim to know it stratifying by sex and assessing how the sex may impact the survival.

Methods: We retrospectively selected all patients >75 who suffered a STEMI treated with primary PCI at our institution. We compared their survival with that of the reference population (general population matched by age, sex, and geographical region). A Cox-regression analysis controlling for clinical factors was performed to know if sex was a risk factor.

Results: Total of 450 patients were studied. Survival at 1, 3, and 5 years of follow-up for patients who survived the first 30 days was 91.22% (CI95% 87.80-93.72), 79.71% (CI95% 74.58-83.92), and 68.02% (CI95% 60.66-74.3), whereas in the reference population it was 93.11%, 79.10%, and 65.01%, respectively. Sex was not a risk factor, Hazard Ratio = 1.02 (CI95% 0.67-1.53; = 0.92).

Conclusions: Life expectancy of patients suffering a STEMI is nowadays intimately linked to survival in the first 30 days. After one year, the risk of death for both men and women seems similar to that of the general population.

Recent studies have suggested that the interaction between diet and an individual's genetic predisposition can determine the likelihood of obesity and various metabolic disorders. The current study aimed to examine the association of dietary branched-chain amino acids(BCAAs) and aromatic amino acids(AAAs) with the expression of the leptin and FTO genes in the visceral and subcutaneous adipose tissues of individuals undergoing surgery. This cross-sectional study was conducted on 136 Iranian adults, both men and women, aged ≥18 years.

Sexual dysfunctions (SD) are common and debilitating side effects of antipsychotics. The current study analyzes the occurrence of antipsychotic-related SD using data from the US Food and Drug Administration (FDA) Adverse Event Reporting System (FAERS). FAERS was queried for sexual dysfunction adverse events (encoded by 35 different MedDRA preferred terms) secondary to amisulpride, aripiprazole, chlorprothixene, clozapine, haloperidol, loxapine, olanzapine, pipamperone, quetiapine, risperidone, and ziprasidone from 2000 to 2023.

Objective: To test whether an artificial intelligence (AI) deep neural network (DNN)-derived analysis of the 12-lead electrocardiogram (ECG) can distinguish patients with long QT syndrome (LQTS) from those with acquired QT prolongation.

Methods: The study cohort included all patients with genetically confirmed LQTS evaluated in the Windland Smith Rice Genetic Heart Rhythm Clinic and controls from Mayo Clinic's ECG data vault comprising more than 2.5 million patients.

Objectives: Tested the prospective relationship of a resilient personality prototype determined prior to disability onset to well-being among persons with and without debilitating functional impairments nine to 10 years later. A resilient profile was expected to predict well-being through its beneficial associations with positive affect, perceived control and social support.

Design: Longitudinal, prospective observation study.

Women experience greater stress and burnout compared to men, particularly at midlife, when gender role expectations may contribute to experiencing stress and burnout. To date, researchers have not empirically examined the associations between gender traits and stereotypes, stress, and burnout among midlife women. Gendered traits and stereotypes were assessed via self-reported questionnaires, along with perceived stress and burnout.
