This case study examines a 60-year-old patient named Thomas, who presents with acute coronary syndrome and several comorbidities, including hypertension, hyperlipidemia, type 2 diabetes mellitus, and a history of rheumatic heart disease. The analysis delves into the pathophysiology of Thomas's symptoms, focusing on the impact of long-term medication use, particularly metformin, and its associated side effects like vitamin B12 deficiency and shortness of breath. The case study also explores the potential for myocardial infarction and atherosclerosis, given the patient's symptoms and medical history, including previous bypass surgeries. Alternative medications and lifestyle adjustments are considered to manage Thomas's condition and alleviate his symptoms.
