117 patients, 89 men and 28 women, with repeated myocardial infarction were followed up for a two year period. The following were taken into consideration: risk factors, number and localization of previous infarctions, interinfarction period, clinical onset of the new infarction, complications, electrocardiographic changes, time of death, causes of death, pathologicoanatomical localization of the new and old infarctions in comparison with the electrocardiographic localization. Statistically significant differences between the two sexes were found for the death of cardiogenic shock--48.9% for men and 13.3 for women (p less than 0.01) and for chronic cardiac failure as a complication of the second myocardial infarction--50.0% for women and 16.1% for men (p less than 0.001). For all other indices the differences were not statistically significant.

Pathogenesis-directed therapy of methylphenidate-induced oxidative heart damage in rats.
Front Pharmacol

Department of Pharmacology, Faculty of Medicine, Erzincan Binali Yildirim University, Erzincan, Türkiye.
Aim: The current study aimed to investigate the protective effects of adenosine triphosphate (ATP), metyrosine, and melatonin on possible methylphenidate cardiotoxicity in rats using biochemical and histopathological methods.
Methods: Thirty rats were separated into five groups: healthy (HG), methylphenidate (MP), ATP + methylphenidate (ATMP), metyrosine + methylphenidate (MSMP), and melatonin + methylphenidate (MLMP). ATP (5 mg/kg) was given intraperitoneally once daily, metyrosine (50 mg/kg) orally twice daily, and melatonin (10 mg/kg) orally once daily.
The Association Between Left Ventricular Global Function Index and Major Adverse Cardiovascular Events Linked to Systemic Inflammation in Acute Coronary Syndrome.

Department of Cardiology, Faculty of Medicine, Hacettepe University, Ankara, Turkey.
We aimed to investigate the association between systemic inflammation and the left ventricular global function index (LVGFI) and evaluate the diagnostic performance of LVGFI for MACEs across the acute coronary syndrome (ACS) spectrum. A total of 1697 patients (794 with ST-segment elevation myocardial infarction [STEMI] and 903 with non-STEMI [NSTEMI]) were evaluated. The LVGFI was calculated using echocardiography.

Interest in obstructive sleep apnea is rising due to its neurocognitive and cardiovascular impacts, including systemic hypertension, myocardial infarction, and cerebrovascular events. Obstructive sleep apnea diagnosis can be suggested through symptoms like snoring, daytime sleepiness, and physical signs like increased neck circumference; however, overnight polysomnography is recommended to confirm. Exhaled breath condensate has emerged as a novel, noninvasive technique for biomarker sample collection.

Spontaneous coronary artery dissection (SCAD) is characterized by intramural hematoma in a coronary artery leading to partial or complete vessel obstruction. A 51-year-old female was hospitalized with acute myocardial infarction and cardiogenic shock. She was diagnosed with severe SCAD, affecting the proximal left coronary artery.
