ABSTRACT
This thorough literature evaluation was prompted by significant research into the complex interactions between estrogen use and myocardial infarction (MI). Estrogen has fascinated researchers because of its possible cardioprotective benefits and its impact on cardiovascular health. In order to clarify the connection between estrogen use and the risk of MI, this review critically examines the body of prior evidence. This review focuses on estrogen and its pivotal role in cardiovascular health, concentrating on lipid metabolism, vasodilation, inflammation, and endothelial function. It examines contentious data about estrogen therapy's heart-protective effects, taking into account age, initiation timing, dosage, and dosage of administration. Genetic and epigenetic influences on MI risk among estrogen users highlight intricate, personalized estrogen effects. The conclusion summarizes the main findings and emphasizes the need for an all-encompassing strategy for initiating and managing estrogen medication. It is crucial to consider patient-specific traits and risk factors to successfully customize treatment regimens. This review sheds vital light on the potential directions for better cardiovascular treatment for postmenopausal women by shedding light on the complex link between estrogen use and myocardial infarction. The review also identifies research gaps and future objectives in this area, highlighting the demand for novel medicines and individualized strategies to improve cardiovascular outcomes.
ABSTRACT
BACKGROUND: Atrial fibrillation (AF) is a prevalent cardiac arrhythmia associated with increased morbidity and mortality. However, factors influencing AF progression and their impact on all-cause mortality in South Indian patients remain poorly understood. METHODS: We conducted a retrospective cohort study involving 500 individuals diagnosed with AF. Patient characteristics, including age, sex, and comorbidities, were collected. Left atrial diameter (LAD) and left ventricular ejection fraction (LVEF) were measured via echocardiography. Participants were followed for a median of three years. Cox proportional hazard regression was used to analyze factors associated with AF progression and all-cause mortality. RESULTS: Of the participants, 60% exhibited persistent or permanent AF, and 40% had paroxysmal AF. The mean age was 63.5 ± 10.8 years, with 60% males and 40% females. Common comorbidities included hypertension (80%), diabetes (50%), and coronary artery disease (35%). The mean LAD was 42.3 ± 5.6 mm and the mean LVEF was 52.7 ± 6.8%; left atrial appendage thrombus (LAAT) was present in 15% of patients. Over the follow-up, 24% experienced all-cause mortality. Multivariate analysis revealed age, hypertension, diabetes, LAD, and LVEF as significant predictors of AF progression (p<0.05). Patients with persistent or permanent AF exhibited a higher risk of progression than those with paroxysmal AF (hazard ratio=1.74, 95% CI, 1.23-2.45). Age, hypertension, heart failure, and AF progression were independent predictors of all-cause mortality (p<0.05). CONCLUSION: Our study identified age, hypertension, diabetes, LAD, and LVEF as independent predictors of AF progression. Additionally, age, hypertension, heart failure, and AF progression independently predicted all-cause mortality. These findings underscore the need for early detection and management of AF progression and comorbidities to improve outcomes in South Indian AF patients. Prospective studies with larger cohorts are warranted to confirm these findings and explore interventions to prevent AF progression and enhance patient outcomes.
ABSTRACT
Diabetic myonecrosis is an infrequently encountered complication of poorly managed type 2 diabetes. Despite its relative rarity, early detection and appropriate management can yield favorable outcomes. This case report details the presentation, diagnosis, and management of a 53-year-old male patient with a history of type 2 diabetes who presented with acute-onset pain, swelling of the muscles, and weakness. Following a battery of laboratory investigations, radiological imaging, and a muscle biopsy, the patient was diagnosed with diabetic myonecrosis. The patient was treated conservatively with analgesics, physiotherapy, and optimization of glycemic control, significantly improving muscle strength and function. This case highlights the necessity of considering diabetic myonecrosis as a potential differential diagnosis in diabetic patients who present with sudden muscle weakness and discomfort.
