Abstract Cardiac tumors are rare entities, among which atrial myxoma (AM) stands as the most frequent, accounting for approximately half of all reported cases. The incidence of AM is estimated to range from 0.001% to 0.3% within the general population, yet only about 0.06% of these cases present with coronary embolic events. We report on a 33-year-old male smoker who experienced acute, severe precordial pain radiating to the left upper limb, lasting for one hour. The electrocardiographic evaluation demonstrated ST-segment […]

Case Report A 32-year-old young man, without cardiovascular risk factors, sought an Emergency Unit due to severe chest pain 30 minutes before admission, without irradiation. Admission vital signs: T 36.1°C, heart rate of 89 bpm and peripheral O2 saturation of 96% in room air. During systematic interrogation, anosmia and ageusia were reported two days ago and fever or any other respiratory symptom was denied. He was previously healthy and denied use of illicit drugs or previous history of angina. He […]

Introduction Three-dimensional echocardiography (3DE) plays an increasingly important role in the diagnosis of valvular heart disease, in the assessment of valvular morphology in an anatomical manner, and in establishing valve repairability, beyond the limitations of conventional two-dimensional echocardiography (2DE). We report the case of a young patient presenting with acute anterior ST-segment elevation myocardial infarction and severe mitral regurgitation (MR) after successful primary percutaneous coronary intervention (PCI) of the left anterior descending artery, whose three-dimensional transesophageal echocardiography (3D TEE) revealed […]

Background: Among dyslipidemias, hypercholesterolemia is considered the main risk factor for cardiovascular diseases in adults. In childhood and adolescence, elevated total cholesterol (TC) and low-density lipoprotein cholesterol (LDL-C) are positively associated with atherosclerosis markers, however, systematic screening for dyslipidemias in these groups is a controversial topic. Objective: To characterize the frequencies, types and severity of dyslipidemias in children and adolescents attended at the Basic Health Units managed by SUS in Campinas/SP. Methods: After an agreement with the Municipal Health Department […]

Abstract Spontaneous coronary artery dissection (SCAD) is considered an often underdiagnosed acute coronary syndrome, with few cases described in literature. Its association with physical exercise among young patients without risk factors or atherosclerotic disease (CAD) is even rarer. For this reason, a study was conducted on the subject, describing the clinical conditions, conduct and evolution regarding the suspicion of spontaneous exercise-related coronary artery dissection in three young patients without risk factors or CAD. Clinical conditions varied, with predominant recurrent chest […]

Clinical aspects This is the case of a young, male patient, smoker, who had hypothyroidism post-treatment with radioactive iodine, who sought medical care due to symptoms of dyspnea and cough for a week; these complaints had been preceded by chest pain at exertion two weeks before. The medical evaluation at the first consultation was notable for the presence of tachycardia and mild leukocytosis in the whole blood count. The chest X-ray was normal despite the presence of dyspnea at rest. […]

Background: A subset of patients who take antiplatelet therapy continues to have recurrent cardiovascular events which may be due to antiplatelet resistance. The effect of low response to aspirin or clopidogrel on prognosis was examined in different patient populations. Objective: We aimed to investigate the prevalence of poor response to dual antiplatelet therapy and its relationship with major adverse cardiovascular events (MACE) in young patients with ST-elevation myocardial infarction (STEMI). Methods: In our study, we included 123 patients under the […]

Abstract Background: Type 1 diabetes mellitus can cause autonomic changes, which can be assessed by heart rate variability. Among the heart rate variability assessment methods, the symbolic analysis and Shannon entropy, based on the Chaotic dynamics, have gained prominence. Objective: To compare heart rate variability indexes, obtained through symbolic analysis and Shannon entropy, in young adults with type 1 diabetes mellitus and healthy young individuals, associated with the analysis of linear indexes; and to verify if there are associations between […]
