Young Male With Sudden Onset Chest Pain and Inferior Wall STEMI (Cardiology)
Dr. Kishan Mishra., MBBS
Medical Case Details:
A 24-year-old male software engineer presented to the emergency department with sudden onset retrosternal chest pain of 45 minutes duration. The pain was crushing in nature, rated 8/10 in intensity, and radiated to the left jaw and left arm. It was associated with profuse sweating, nausea, and a sense of impending doom. He had no previous history of hypertension, diabetes, or cardiac disease. He smoked around 5 to 6 cigarettes daily for the past three years. Family history was significant for myocardial infarction in his father at the age of 42 years. There was no history of fever, cough, syncope, or recreational drug use. On examination, blood pressure was 104/70 mmHg, pulse rate was 110 bpm and regular, and oxygen saturation was 97% on room air. Mild pallor was present. There was no raised JVP, lungs were clear, and heart sounds were normal without murmurs. ECG showed ST elevation in leads II, III, and aVF with reciprocal changes in leads I and aVL, suggestive of inferior wall STEMI. Troponin I was elevated at 1.8 ng/mL. Chest X-ray showed a normal cardiac silhouette. A provisional diagnosis of inferior wall STEMI in a young adult was made, with possible etiologies including coronary vasospasm or premature atherosclerotic disease. The patient was immediately started on aspirin 325 mg, clopidogrel 600 mg loading dose, IV heparin, and sublingual nitrate, following which he was shifted for emergency PCI.Discussions

This is a very important and well-constructed clinical scenario because it highlights that acute ST-Elevation Myocardial Infarction can occur even in very young adults and should never be dismissed purely because of age. The presentation is classical for acute coronary syndrome: crushing retrosternal chest pain radiating to the jaw and arm, diaphoresis, nausea, autonomic symptoms, and diagnostic ECG changes with inferior ST elevation and reciprocal changes strongly support inferior wall STEMI, likely involving the right coronary artery. Immediate administration of dual antiplatelet therapy, anticoagulation, nitrates, and urgent PCI was entirely appropriate and follows current guideline-based management.
Although the patient lacks traditional long-standing risk factors such as diabetes or hypertension, he still has several important contributors to premature coronary artery disease: active smoking, strong family history of premature myocardial infarction, possible genetic dyslipidemia, stress-related lifestyle factors, and potential undiagnosed metabolic abnormalities. In a 24-year-old, the differential should remain broad and include premature atherosclerosis, coronary vasospasm, spontaneous coronary artery dissection, hypercoagulable states, congenital coronary anomalies, myocarditis mimicking STEMI, and less commonly substance-related vasospasm despite denial of recreational drug use.
This case also emphasizes the importance of aggressive secondary prevention after PCI. The patient will require high-intensity statin therapy, smoking cessation counseling, cardiac rehabilitation, echocardiographic assessment of LV function, and evaluation for inherited lipid disorders such as familial hypercholesterolemia given the father’s MI at 42 years. Long-term lifestyle modification is crucial because young STEMI survivors remain at high lifetime cardiovascular risk despite successful revascularization.
Academically, this is an excellent teaching case because it demonstrates:
STEMI can occur at very young age
Family history is a major independent risk factor
ECG recognition remains lifesaving
Early reperfusion therapy dramatically improves outcomes
Atypical age should never delay activation of PCI pathways.
Thanks.
