Introduction. Ischemic heart disease is the leading cause of death with increasing prevalence. Acute myocardial infarction is a consequence of prolonged acute myocardial ischemia, which appears secondary to an imbalance between oxygen consumption and intake at this level.
Case report. We present the case of a male patient, aged 53 years old, admitted in the Cardiovascular Recovery Clinic for moderate dyspnea, intermittent dizziness and muscle pain predominantly in the lower limbs. Regarding his medical history, he suffered an antero-lateral myocardial infarction due to excessive physical effort, which was trombolysed. Following the remission of the acute episode, the evolution over the next 6-12 months was towards heart failure clinically manifested by dyspnea. Considering the presence of heart failure associated with severely diminished ejection fraction, the medication is adjusted and Sacubitril/Valsartan is introduced at a dose of 49/51 mg twice a day, under which our patient presents with both clinical and echocardiography improvement. Cardio-pulmonary stress testing is the most accurate as it provides the best information regarding functional capabilities, beyond the ejection fraction of the left ventricle. Following the treatment with RNAi (angiotensin receptor-neprilysin inhibitor), the parameters evaluated during the stress test were improved, which is clinically transposed by improving the quality of life and implicitly the long-term prognosis.
Conclusion. The particularity of this case consists in the occurrence of myocardial infarction at a young age (36 years) in a patient without a heredocolateral history or associated risk factors at that time. The association of ARNI (Sacubitril / Valsartan) in the therapeutic scheme has determined a clinical improvement, as well as paraclinical especially regarding the echocardiographic parameters (the ejection fraction increased from 25% to 40% at the end of the evaluation).
