Abstract

Background

Heart disease, which affects approximately 4% of pregnancies, is the leading non-obstetric cause of maternal death. It is estimated that 40% of these deaths could be prevented with a better understanding of pregnancy risks.

Objectives

To develop the Brazilian Registry of Heart Diseases in Pregnancy (REBECGA) to study the prevalence, complications, and maternal mortality associated with heart diseases during pregnancy and postpartum.

Methods

A multicenter retrospective study of pregnancy and postpartum follow up until 12 months after delivery in women with heart diseases, including analysis of predictive variables for maternal outcomes. A two-tailed significance level of 5% was adopted for statistical analysis.

Results

A total of 638 pregnant women were included, with the following diagnoses: valvular disease (37.8%), congenital heart diseases (35.7%), arrhythmias without structural heart damage (14.7%), cardiomyopathies (11.3%), and other heart diseases (6.4%). The main complications were heart failure (16.7%), arrhythmia (10.7%), and syncope (8.0%), with 18 maternal deaths (2.8%), 10 of which occurred during the postpartum period. Cesarean delivery was indicated in 62.9% of cases, with 25.7% preterm births and 3.2% fetal losses. Multivariate analysis identified WHO class IV risk classification (OR 3.51; 95% CI 1.75–7.04; p < 0.001); NYHA class III/IV (OR 2.27; 95% CI 1.12–4.60; p = 0.023), and pulmonary hypertension (OR 2.45; 95% CI 1.05–5.70; p = 0.037) as predictive variables for maternal complications and deaths.

Conclusions

REBECGA highlighted the prevalence of valvular disease, heart failure as the main complication, the postpartum period as a critical time for maternal deaths, and identified predictive risk variables for adverse pregnancy outcomes in women with heart disease.

OBJECTIVE: Describe clinical characteristics of patients (P) admitted to hospital with suspected acute coronary syndrome (ACS), identifying medical treatment and in-hospital mortality. METHODS: Evaluated were 860 patients with ACS from January through December, 2003. We evaluated baseline characteristics, ACS mode of presentation, medication during hospital stay, indication for clinical treatment or myocardial revascularization (MR) and in-hospital mortality. RESULTS: Five hundred and three (58.3%) were male, mean age 62.6 years (± 11.9). Seventy-eight (9.1%) were discharged with the diagnosis of acute ST-elevation myocardial infarction (STEMI), 238 (27.7%) with non-ST-elevation myocardial infarction (non-STEMI), 516 (60%) with unstable angina (UA), two (0.2%) with atypical manifestations of ACS and 26 (3%) with non-cardiac chest pain. During hospitalization, 87.9% of patients were given a beta-blocker, 95.9% acetylsalicylic acid, 89.9% anti-thrombin therapy, 86.2% intravenous nitroglycerin, 6.4% glycoprotein (GP) IIb/IIIa receptor inhibitor, 35.9% clopidogrel, 77.9% angiotensin-converting enzyme inhibitor, and 70,9% statin drugs. Coronary arteriography was performed in 72 patients (92.3%) with STEMI, and in 452 (59.8%) with non-STEMI ACS (p< 0.0001). Myocardial revascularization (MR) surgery was indicated for 12.9% and percutaneous coronary intervention for 26.6%. In-hospital mortality was 4.8%, and no difference was recorded between the proportion of deaths among patients with STEMI and non-STEMI ACS (6.4% versus 4.8%; p = 0.578). CONCLUSION: In this registry, we provide a description of ACS patient, which allows the evaluation of the demographic characteristics, medical treatment prescribed, and in-hospital mortality. A greater awareness of our reality may help the medical community to adhere more strictly to the procedures set by guidelines.
