Background: Adverse pregnancy outcomes (APOs), hypertensive disorders of pregnancy, gestational diabetes mellitus, and preterm birth are associated with ischemic heart disease in later life.
Objectives: The authors aimed to study the features of premature myocardial infarction (MI) among women with and without prior APOs.
Methods: We performed a retrospective analysis of women with premature MI (<65 years of age) referred for left heart catheterization matched with a database of abstracted pregnancy data. We compared MI characteristics and epicardial coronary anatomy between women with and without APOs during their index pregnancy and evaluated time from delivery to MI.
Results: Of 391 women with premature MI and associated coronary angiography (age: 49 ± 8 years), 154 (39%) had a prior APO (hypertensive disorders of pregnancy n = 78, preeclampsia n = 35, gestational diabetes mellitus n = 28, and preterm birth n = 48). Women with APO history had a higher prevalence of diabetes (33% vs 16% without APO; = 0.001) and presented earlier with MI following delivery (19.6 [IQR: 14.3-23.5] years vs those without APO 21.5 [IQR: 17.0-25.4] years; = 0.012), driven by preeclampsia (17.1 [IQR: 12.7-22.4] years, = 0.010). Women with and without APOs had similar MI features including rates of ST-segment elevation MI, obstructive and multi-vessel coronary artery disease, percutaneous coronary intervention, and shock.
Conclusions: Among women with premature MIs, 39% had a history of an APO. Women with APO history presented sooner after pregnancy but had similar MI characteristics vs those without APOs. Pregnancy history may identify women who warrant early, aggressive cardiovascular disease prevention.

Introduction: Despite its low prevalence, premature myocardial infarction (MI) bears serious social consequences and shares different pathophysiology.
Objectives: The aim of the study was to evaluate young MI patients in terms of clinical characteristics and long-term outcomes.
Patients And Methods: This study is an observational research covering 221 patients <45 years old [16.

American culture encourages overconsumption, fueled by ubiquitous availability and pervasive marketing of ultra-processed foods and other addictive substances. This chronic overindulgence has contributed to rising rates of obesity, type 2 diabetes (T2D), substance abuse, mental health disorders and premature mortality. Glucose-like peptide-1 agonists (GLP-1RAs) affect the brain's reward pathway that mediates addiction to foods and various other substances.

Article Synopsis
- Impaired calcium (Ca) handling in heart cells is a key feature of heart failure (HF), leading to issues like weakened heart contractions and irregular heartbeats.
- The study used transgenic mice with a mutation affecting a calcium regulator (phospholamban) to understand how defects in calcium cycling contribute to HF, noting that these mice experience severe and fast-progressing heart failure.
- Early treatment aimed at correcting calcium cycling using Raf kinase inhibitor protein (RKIP) was found to delay heart cell damage and improve overall health of the mice, indicating that addressing Ca dynamics early on could be crucial for preventing further complications in heart failure.

Background: Hyperglycemia is a condition in which blood sugar levels increase excessively due to a variety of factors, one of which is the body's inability to regulate insulin properly. Diabetes closely relates to this condition, which significantly contributes to premature death and disability. Long-term diabetes treatment accompanied by a strict diet provides real results in controlling blood glucose levels but can cause side effects.

Background: Ventricular arrhythmia is a common type of arrhythmia observed in clinical practice. It is primarily characterized by premature ventricular contractions, ventricular tachycardia, and ventricular fibrillation. Abnormal formation or transmission of cardiac electrical impulses in patients affects cardiac ejection function.
