The vast majority of patients can go safely through pregnancy and delivery as long as adequate pre-pregnancy evaluation and specialized high-quality care during pregnancy and delivery are available. Pregnancy outcomes were markedly worse in patients with CMP and in developing countries.

Aims To validate the modified World Health Organization (mWHO) risk classification in advanced and emerging countries, and to identify additional risk factors for cardiac events during pregnancy. Methods and results The ongoing prospective worldwide Registry Of Pregnancy And Cardiac disease (ROPAC) included 2742 pregnant women (mean age ± standard deviation, 29.2 ± 5.5 years) with established cardiac disease: 1827 from advanced countries and 915 from emerging countries. In patients from advanced countries, congenital heart disease was the most prevalent diagnosis (70%) while in emerging countries valvular heart disease was more common (55%). A cardiac event occurred in 566 patients (20.6%) during pregnancy: 234 (12.8%) in advanced countries and 332 (36.3%) in emerging countries. The mWHO classification had a moderate performance to discriminate between women with and without cardiac events (c‐statistic 0.711 and 95% confidence interval (CI) 0.686–0.735). However, its performance in advanced countries (0.726) was better than in emerging countries (0.633). The best performance was found in patients with acquired heart disease from developed countries (0.712). Pre‐pregnancy signs of heart failure and, in advanced countries, atrial fibrillation and no previous cardiac intervention added prognostic value to the mWHO classification, with a c‐statistic of 0.751 (95% CI 0.715–0.786) in advanced countries and of 0.724 (95% CI 0.691–0.758) in emerging countries. Conclusion The mWHO risk classification is a useful tool for predicting cardiac events during pregnancy in women with established cardiac disease in advanced countries, but seems less effective in emerging countries. Data on pre‐pregnancy cardiac condition including signs of heart failure and atrial fibrillation, may help to improve preconception counselling in advanced and emerging countries.

Although mortality was only 1.9% during pregnancy, ≈50% of the patients with severe rheumatic MS and 23% of those with significant MR developed heart failure during pregnancy. Prepregnancy counseling and considering mitral valve interventions in selected patients are important to prevent these complications.

Background The prevalence of ischemic heart disease (IHD) in women of child‐bearing age is rising. Data on pregnancies however are scarce. The objective is to describe the pregnancy outcomes in these women. Methods and Results The European Society of Cardiology‐EURObservational Research Programme ROPAC (Registry of Pregnancy and Cardiac Disease) is a prospective registry in which data on pregnancies in women with heart disease were collected from 138 centers in 53 countries. Pregnant women with preexistent and pregnancy‐onset IHD were included. Primary end point were maternal cardiac events. Secondary end points were obstetric and fetal complications. There were 117 women with IHD, of which 104 had preexisting IHD. Median age was 35.5 years and 17.1% of women were smoking. There was no maternal mortality, heart failure occurred in 5 pregnancies (4.8%). Of the 104 women with preexisting IHD, 11 women suffered from acute coronary syndrome during pregnancy. ST‐segment‒elevation myocardial infarction were more common than non‒ST‐segment‒elevation myocardial infarction, and atherosclerosis was the most common etiology. Women who had undergone revascularization before pregnancy did not have less events than women who had not. There were 13 women with pregnancy‐onset IHD, in whom non‒ST‐segment‒elevation myocardial infarction was the most common. Smoking during pregnancy was associated with acute coronary syndrome. Caesarean section was the primary mode of delivery (55.8% in preexisting IHD, 84.6% in pregnancy‐onset IHD) and there were high rates of preterm births (20.2% and 38.5%, respectively). Conclusions Women with IHD tolerate pregnancy relatively well, however there is a high rate of ischemic events and these women should therefore be considered moderate‐ to high‐risk. Ongoing cigarette smoking is associated with acute coronary syndrome during pregnancy.

Background PTEN gene triggers cells to undergo apoptosis and promotes myocardial dysfunction. Several TNF family cytokines are elevated during acute myocardial infarction (AMI). Their role in predicting subsequent prognosis in these setting remains poorly understood. We assessed serum levels of PTEN gene activity & TNF-α in acute ST elevation myocardial infarction and determined the impact of their levels on both left ventricular function and the clinical outcome in these patients. Methods and results Seventy patients with AMI and seventy persons as control group were subjected to: ECG, echocardiography, serum TNF-α and PTEN gene assessment. Patients were classified into: Group I (n = 32): All had left ventricular systolic failure. Group II (n = 38): without left ventricular systolic failure. Group I had a statistically significant higher serum levels of both TNF-α & PTEN gene activity as compared to group II. EF% at presentation was weakly correlated with serum levels of both markers in both groups. However at follow up, EF% in group I showed a significant negative correlations with both serum levels of TNF-α and PTEN gene activity (r = 0.77 & r = 0.67, respectively). During one year follow, 5 patients died of cardiovascular causes and 6 patients had recurrent hospitalization with heart failure. These patients had statistically significant increased serum levels of TNF-α & PTEN gene activity levels as compared by other patients. Conclusions Patients with acute myocardial infarction had statistically significant increased serum levels of PTEN & TNF-α gene activity. Both markers predict worsening of left ventricular systolic functions, development of heart failure and death.
