This case study presents a 56-year-old male, Mr. Crawford, with a history of hypertension and obesity, who presented with symptoms indicative of an acute myocardial infarction (MI). The case details his clinical presentation, including prolonged chest pain, shortness of breath, and elevated blood pressure. Diagnostic tests, such as ECG and cardiac enzyme analysis, confirmed an ST-elevation myocardial infarction (STEMI). The pathophysiology explains the underlying mechanisms, including atherosclerotic plaque rupture and thrombus formation. The management involved immediate interventions like heparin, reteplase, morphine, and aspirin, followed by continuous monitoring and thrombolytic therapy. The study further elaborates on the biochemical and morphological changes associated with myocardial ischemia, emphasizing the importance of early antithrombotic and anticoagulant treatment. The discussion covers the role of cardiac biomarkers, electrolyte imbalances, and potential complications such as cardiogenic shock and pulmonary congestion. The case concludes with relevant references, providing a comprehensive overview of the diagnosis, management, and pathophysiology of myocardial infarction.
