Background: Coronary artery disease is a major public health concern worldwide. In Africa, varying rates of progression increased in different countries. In Angola, although the epidemiological scenario is dominated by infectious diseases, the prevalence of coronary artery disease is increasing with notable impacts, requiring the creation of mechanisms to face this reality in a country where lack of specific infrastructure is still a challenge. The objective of this study was to describe the experience of primary angioplasty in patients with acute myocardial infarction in an Angolan tertiary care center. Methods: This was a descriptive, longitudinal, retrospective study, involving 165 patients diagnosed with acute myocardial infarction between 2012 and 2019. Variables were age, sex, risk factors, angiographic and procedure-related characteristics, and main complications. Results: The mean age was 58.3±6.8 years, and males predominated (75.8%). Hypertension (69.7%), dyslipidemia (35.2%), smoking (32.7%) and diabetes (29.7%) were more prevalent. The anterior location was the predominant topography of infarction (49.7%). Single vessel disease was the most common pattern (50.9 %). The left anterior descending artery was the most often involved vessel (49.7%). The door-to-balloon time was 46.6±32.4 minutes. In the multivariate analysis, anterior myocardial infarction (p=0.033), diabetes (p=0.004), age ≥60 years (p≤0.001) and post-coronary intervention final TIMI flow Conclusion: Percutaneous coronary intervention in the context of acute myocardial infarction in Angola is a reality, but the number of procedures performed is not enough given the current great demand.

A Dissecção coronária espontânea é uma rara causa de síndrome coronária aguda não relacionada com a aterosclerose, diagnosticada em 20-30% das mulheres em idade reprodutiva antes dos 50 anos. Desde sua primeira descrição há mais de meia década por Harold Pretty, vem sendo palco de inúmeros desafios quanto ao diagnóstico precoce e a melhor abordagem terapêutica. A coronariografia constitui o padrão-ouro no diagnóstico dessa entidade e o tratamento conservador mostra-se seguro, e a intervenção coronária percutânea está associada a altas taxas de insucesso. Apresentamos o caso de uma puérpera angolana de 41 anos diagnosticada com dissecção coronária espontânea tratada de forma conservadora.

Os Dispositivos Eletrônicos Cardíaco Implantáveis (DECI) são grandes aliados no tratamento de distúrbios do ritmo cardíaco, não obstante a isso, vem sofrendo alterações para ampliar as indicações em contextos variáveis como na disfunção sistólica ventricular. Este estudo objetiva caracterizar clínico-epidemiológico os pacientes submetidos a implantação de dispositivos eletrônicos cardíaco no período de 2015 a 2018, realizado através de estudo descritivo, transversal, quantitativo de carácter retrospectivo. No total foram 133 registros de pacientes submetidos a implantação desses dispositivos.

Wellens syndrome was described by Zwaan, Bär and Wellens, in 1982. On the electrocardiogram, T wave morphological alterations are observed in precordial leads, suggesting severe proximal stenosis of the left anterior descending coronary artery and an imminent risk of acute myocardial infarction and/or sudden death, with slight or no alteration in serum troponin. Its early recognition and management with early myocardial reperfusion avoid unfavorable outcomes. Percutaneous coronary intervention and surgical myocardial revascularization are the most used strategies for treatment. The authors describe two cases of types A and B Wellens syndrome treated with different reperfusion strategies.
