The article focuses on the relationship between cardiac reserve and cardiorespiratory fitness (CRF) in patients who have experienced reperfused ST-elevation myocardial infarction (STEMI). A study involving fifty-six patients assessed cardiac reserve through Doppler echocardiography and CRF via a symptom-limited cardiopulmonary exercise test conducted approximately six weeks post-STEMI. Results indicated significant correlations between cardiac reserve metrics, such as stroke volume and cardiac output, and CRF measures, including peak oxygen uptake and ventilatory efficiency. The findings suggest that enhancing cardiac reserve may also improve CRF in this patient population.
