A middle-aged male with no immediate cardiovascular risk factors presented for a routine annual wellness examination with his primary care provider. He had severe fatigue but denied exertional chest pain, dyspnea, palpitations or exercise intolerance; his overall cardiovascular risk profile prompted additional evaluation.
Given the absence of symptoms but the presence of fatigue and family history of risk factors, the patient was referred to Norton Heart & Vascular Institute for further cardiovascular assessment.
This case illustrates a common challenge in preventive cardiology: identifying clinically significant coronary artery disease in patients without classic ischemic symptoms.
Despite reporting excellent functional status and maintaining normal daily activities, noninvasive cardiovascular evaluation raised concern for obstructive coronary artery disease. Subsequent diagnostic testing demonstrated advanced atherosclerotic disease that placed the patient at substantial risk for myocardial infarction if left untreated.

The patient underwent comprehensive cardiovascular evaluation, including advanced cardiac imaging. Initially the patient had a coronary calcium screening that indicated a need for further evaluation. The patient then underwent a coronary CT angiography supported by CT fractional flow reserve imaging and diagnostic cardiac catheterization.
Diagnostic catheterization confirmed severe coronary artery disease requiring intervention. After multidisciplinary evaluation, the interventional cardiology team performed coronary revascularization to restore myocardial perfusion.
Providers now have the ability to order CCTA for your patients in Kentucky and Southern Indiana. Get answers via this advanced cardiac diagnostic without sending patients to the emergency department or waiting for a cardiology appointment. See referral guidance here and more information.
Following the procedure, the patient was initiated on guideline-directed medical therapy, including aggressive lipid management, antiplatelet therapy and optimization of modifiable cardiovascular risk factors. He also received counseling regarding nutrition, physical activity, blood pressure management and long-term preventive follow-up.
This case highlights the importance of integrating preventive screening, risk stratification and timely referral from routine primary care to identify high-risk patients before the development of acute coronary syndrome.
The patient recovered without complication and returned to normal daily activities.
Early identification of advanced coronary artery disease allowed intervention before the occurrence of myocardial infarction or irreversible myocardial injury. Ongoing follow-up focuses on secondary prevention through risk factor modification, medication adherence and continued cardiovascular surveillance.
This case demonstrates how routine preventive care and appropriate cardiovascular referral can identify significant occult coronary artery disease in asymptomatic individuals, potentially preventing a life-threatening cardiac event and improving long-term cardiovascular outcomes.
