SUDDEN DECREASE IN EXERCISE TOLERANCE—A CASE STUDY ON ANOCA

Abstract

This case study describes the evolution of a 45-year-old patient who presented to the hospital with a
severe inferior respiratory tract infection. The interpretation of the electrocardiogram led to a
reconsideration of the medical history and the identification of anginal pain, resulting in referral to the
cardiology department. The investigations carried out (biochemical tests, stress test, and coronary
angiography) established the diagnosis of angina with non-obstructive coronary arteries (ANOCA).
The uniqueness of the case lies in the association of this diagnosis with a combination of traditional
cardiovascular risk factors (hypertension, dyslipidemia) and non-traditional factors (chronic
inflammation, psychosocial stress). The average duration for establishing the diagnosis of ANOCA
remains prolonged, contributing to the decrease in patient’s quality of life. This case emphasizes the
need for more efficient educational, diagnostic, and therapeutic strategies. It is essential to increase
public awareness regarding the importance of addressing subtle symptoms that can be mistaken for the
effects of aging and to reduce diagnostic delays in order to improve cardiovascular prognosis
