Background: Clomiphene citrate (CC) is commonly prescribed for ovulation induction. It is considered safe, with minimal side effects. Thromboembolism is a rare but life-threatening complication that has been reported after ovulation induction with CC. Spontaneous coronary thrombosis or thromboembolism with subsequent clot lysis has been suggested as one of the most common causes of myocardial infarction (MI) during pregnancy, with a subsequently normal coronary angiogram.
Case: A 33-year-old woman with a 5-week gestation had recently received CC for ovulation induction and presented with chest pain. An electrocardiogram showed a lateral and anterior wall myocardial infarction. Cardiac enzymes showed a peak rise in troponin I to 9.10 ng/mL. An initial exercise stress test was normal. At the time of admission, the patient was at high risk of radiation injury to the fetus, so a coronary angiogram was postponed until the second trimester. It showed normal coronary vessels.
Conclusion: This appears to be the first reported case documenting a possible association between CC and myocardial infarction. Thrombosis might be a rare but hazardous complication of CC. Given this life-threatening complication, appropriate prophylactic measures should be used in high-risk woman undergoing ovarian stimulation.

Importance: Outcomes in patients with diabetes after fractional flow reserve (FFR)-guided percutaneous coronary intervention (PCI) using current-generation drug-eluting stents (DES) compared with coronary artery bypass grafting (CABG) are unknown.
Objectives: To investigate the relative treatment effect of PCI vs CABG according to diabetes status with respect to major adverse cardiac and cerebrovascular events (MACCE) at 3 years and to evaluate the impact of the SYNTAX score.
Design, Setting, And Participants: This is a prespecified subgroup analysis of the FAME (Fractional Flow Reserve vs Angiography for Multivessel Evaluation) 3 trial, an investigator-initiated, randomized clinical trial conducted at 48 centers worldwide.

Acute myocardial infarction, a leading cause of death globally, is often associated with cardiometabolic disorders such as atherosclerosis and metabolic syndrome. Metabolic treatment of these disorders can improve cardiac outcomes, as exemplified by the GLP-1 agonist semaglutide. Fibroblast growth factor 21 (FGF21), a novel metabolic regulator, plays pivotal roles in lipid mobilization and energy conversion, reducing lipotoxicity, inflammation, mitochondrial health, and subsequent tissue damage in organs such as the liver, pancreas, and heart.

Introduction: Acute coronary syndrome refers to a group of diseases characterized by sudden, decreased blood supply to the heart muscle that results in cell death, also known as acute myocardial infarction. This results in severe chest pain or discomfort, with the subsequent release of cardiac biomarkers, and alterations in the electrocardiogram. It can cause diminished heart function and mortality if not treated properly with suitable measures.

Radiofrequency ablation (RFA) is an important therapeutic modality for atrial fibrillation (AF), widely utilized in clinical practice due to its safety and significant efficacy. However, post-procedural complications may arise, influenced by anatomical positioning and the intensity of ablation energy, with atrioesophageal fistula (AEF) being particularly rare yet severe. This case report describes a unique instance of a patient developing AEF following AF ablation, accompanied by ischemic stroke and myocardial infarction.

Objective: This study aimed to evaluate the correlation between aerobic exercise intensity based on the 6 min walk test (6MWT) and the anaerobic threshold (AT)-based equivalent in patients with acute myocardial infarction (AMI). The feasibility of using the 6MWT for exercise prescription in primary care settings was also investigated.
Methods: A retrospective analysis was conducted on data from AMI patients, including statistics on all values of the cardiopulmonary exercise test and 6MWT parameters.
