Objective: REMEHIP is a prospective, multicentre registry on pulmonary hypertension. The main objective will be to identify the clinical profile, medical care, therapeutic trends and outcomes in adult and pediatric Mexican patients with well-characterized pulmonary hypertension. Methods: REMEHIP a multicenter registry began in 2015 with a planned recruitment time of 12 months and a 4-year follow-up. The study population will comprise a longitudinal cohort study, collecting data on patients with prevalent and incident pulmonary hypertension. Will be included patients of age >2 years and diagnosis of pulmonary hypertension by right heart catheterization within Group 1 and Group 4 of the World Health Organization classification. The structure, data collection and data analysis will be based on quality current recommendations for registries. The protocol has been approved by institutional ethics committees in all participant centers. All patients will sign an informed consent form. Currently in Mexico, there is a need of observational registries that include patients with treatment in the everyday clinical practice so the data could be validated and additional information could be obtained versus the one from the clinical trials. In this way, REMEHIP emerges as a link among randomized clinical trials developed by experts and previous Mexican experience. [ABSTRACT FROM AUTHOR]

Objective: RENASICA III is a prospective, multicenter registry on acute coronary syndromes (ACS). The main objective will be to identify the outcome in tertiary and community hospitals and perform strategies to improve quality of care in Mexico. Methods: RENASICA III will enroll 8000 patients in public health and private hospitals. The registry began in November 2012 with a planned recruitment during 12 months and a 1-year follow-up. The study population will comprise a consecutive, prospective cohort of patients >18 years with ACS final diagnosis and evidence of ischemic heart disease. The structure, data collection and data analysis will be based on quality current recommendations for registries. The protocol has been approved by institutional ethics committees in all participant centers. All patients will sign an informed consent form. Currently in Mexico, there is a need of observational registries that include patients with treatment in the everyday clinical practice so the data could be validated and additional information could be obtained versus the one from the clinical trials. In this way, RENASICA III emerges as a link among randomized clinical trials developed by experts and previous Mexican experience. [ABSTRACT FROM AUTHOR]

Objective: To describe the clinical-epidemiologic profile and the process of care of the non-ST elevation acute coronary syndromes in a tertiary hospital. Method: We analyzed the clinical information, the risk stratification and diagnostic methods, the revascularization therapy and the prescription trends at discharge, of patients with non-ST elevation acute coronary syndromes cared for in one year. Results: Two hundred and eighty-three patients with mean age of 58 years were included (63% men). The largest number of non-ST elevation acute coronary syndromes (88.6%) was found between 50 to 59 years of age. The most common risk factor was hypertension; 82.5% of the patients had a low-intermediate TIMI score; residual ischemia was demonstrated in 37% and coronary obstructions were seen in 80 patients (70%). In 90%, a percutaneous coronary intervention was performed, mainly with drug-eluting Stents (87.5%). At discharge, even though antiplatelet agents and statins were prescribed in more than 90%, other drugs were indicated in a few more than 50% of patients. Conclusions: In this population, non-ST elevation acute coronary syndromes predominates in relatively young men, often with hypertension. To stratify risk, to look for residual ischemia and to revascularize with drug-eluting stents are common practices, but the evidence-based guidelines compliance is still suboptimal.

Introduction: Data regarding management characteristics of non-ST elevation acute coronary syndromes (NSTE ACS) in Mexican, Hispanic and Non- Hispanic white patients are scarce. Methods: We sought to describe the clinical characteristics, process of care, and outcomes of Mexicans, Hispanics and non-Hispanic whites presenting with NSTE ACS at Mexican and US hospitals. We compared baseline characteristics, resource use, clinical practice guidelines (CPGs) compliance and in-hospital mortality among 3 453 Mexicans, 3 936 Hispanics and 90, 280 non- Hispanic whites with NSTE ACS from the RENASICA and CRUSADE registries. Results: Mexicans were younger with a different cardiovascular risk profile, fewer incidences of hypertension (p<0.001), hiperlipidemia (p<0.001), renal failure (p<0.001) and prior revascularization (p<0.001) but were more likely to be smoking compared with Hispanics and non-Hispanic white populations. Mexicans and Hispanics had a higher incidence of diabetes (p<0.001). At clinical presentation Mexican patients were more likely to have ST depression (p<0.001) but less likely to have left ventricular dysfunction (p<0.001) and troponin stratification (p<0.001). Regarding CPGs compliance, aspirin was used in 90% of patients in all groups, but clopidogrel or unfractionated or low-molecular weight heparin in 50% of patients or less. Mexican patients were less likely to receive glycoprotein IIb/IIIa inhibitors and revascularization. In spite of clinical differences and therapeutic trends, cardiovascular mortality was similar among all groups (Mexicans 4%, Hispanics 4% and non-Hispanic white 5%). In all groups of patients, a poor CPGs compliance was observed. Conclusions: In a post-hoc analysis, Mexican patients with NSTE ACS had a different cardiovascular risk factor profile and clinical presentation, and less intensive in - hospital treatment than Hispanic and non-Hispanic white patients. However, these differences do not appear to affect in - hospital mortality. [ABSTRACT FROM AUTHOR]
