Prediction of 10-year risk of hard coronary events among Saudi adults based on prevalence of heart disease risk factors.

AIM: Cardiovascular disease is becoming the lead cause of mortality and morbidity worldwide, and developing countries are the main contributors to this trend. Saudi Arabia, which is considered a rapidly developing country, faces progressive urbanization and the adoption of a westernized lifestyle, factors which contribute to the rising burden of cardiovascular disease. Our study evaluates the prevalence of coronary risk factors and predicts hard coronary artery events over 10 years in an urban Saudi cohort. METHODS: A cross-sectional observational study was conducted on a Saudi population. The study involved Saudi subjects aged more than 20 years without a history of coronary heart disease. Demographic variables and hard coronary events (HCE) risk factors were measured. Each subject's 10-year HCE risk was estimated by means of the Framingham Risk Score (FRS). RESULTS: A total of 4932 subjects (2215 men and 2717 women) were examined, the majority (85%) of whom were less than 40 years old. The risk of developing HCE within the next 10 years was low in 92.6% of subjects, intermediate in 3.2% and high in 4.1%. On considering diabetes as coronary heart disease (CHD) risk-equivalent, 26% of subjects were at high risk for hard coronary events in 10 years. The HCE risk progressively increased with age and was higher in men. CONCLUSIONS: Our study, the first to estimate the 10-year risk of HCE among adults in an emerging country, determined that a significant proportion of a younger aged population is at risk for the development of hard coronary events. Public awareness programs to control risk factors are warranted.

Metastatic adenocarcinoma presenting as choroidal mass and recurrent cardiac tamponade.

Cardiac tamponade is an unusual earliest presentation of undiagnosed metastatic adenocarcinoma of unknown origin. Malignant pericardial effusion requiring drainage is also a poor prognostic marker with reported median survival of 6.1 months. A choroidal mass may be the presenting sign of systemic malignancy; the diagnosis of metastatic ocular tumour is important as it portends poor prognosis. We are reporting an unusual presentation of an undiagnosed metastatic adenocarcinoma presenting in an elderly male primarily with loss of vision due to choroidal mass causing retinal detachment and repeated episodes of dyspnea due to recurrent pericardial effusion causing cardiac tamponade. Fluid analysis from pleura and breast biopsy revealed evidence of metastatic adenocarcinoma. Immunohistochemistry finding were suggestive of possible lung or gastrointestinal tract as a primary source. Imaging studies showed widely spread malignancy involving abdominal viscera, mediastinum, lung, pericardium, choroid and brain. He showed features of pericardial constriction on echocardiography after fluid drainage due to pericardial infiltration. He expired before he could have received palliative chemotherapy.
