Case of early uncomplicated multivascular nonobstructive coronary atherosclerosis in young male: novel aspects of noninvasive diagnostic.

This clinical report demonstrates the case of nonobstructive coronary artery disease in a 38-year-old male with the only complaint of an episodical increase in blood pressure. A combination of risk factors raised the suspicion of nonobstructive coronary artery disease. It was substantiated by the modified stress test which consists of electrocardiography, echocardiography, laser Doppler flowmetry, pulse oxymetry, capnometry, lactate measurement, and blood pressure monitoring while cycling. Only afterward, the patient passed over coronary computed tomography angiography, which confirmed the suspected diagnosis precisely. Based on the current case, we aimed to increase the awareness of physicians about nonobstructive coronary artery disease and propose an algorithm for nonobstructive coronary atherosclerosis screening.
