Filter by:This prospective observational study will evaluate and compare the sensitivity and specificity of the Modified TIMI, HEART and SACS Scores for accurately predicting the presence and absence of obstructive coronary artery disease (OCAD) as diagnosed during coronary angiography in the cardiac catheterization suite. In addition, we plan to determine if a variant of SACS, HEART, TIMI, or a hybrid score resulting from combining formulas from two or all three scores yields a new tool that exceeds the predictive performance of all three current models for determining the absence or presence of OCAD.
This study evaluates the feasibility and acceptability of a 12-week Tai Chi intervention for patients who have recently had a heart attack and are not participating in a standard cardiac rehabilitation program. Half of the 75 patients will be randomly assigned to the Tai Chi condition and the other half will be assigned to 12 weeks of Health Education. In addition to examining feasibility and acceptability, the investigators will evaluate the impact of participation in the Tai Chi condition on measures of cardiac health, physical function, self-reported health behaviors, and mental health as compared to Health Education within the context of this developmental/exploratory study.
At the periphery of the city of São Paulo, in-hospital mortality in acute myocardial infarction is estimated to range between 15% and 20% due to difficulties inherent to delayed answer at a large metropolis. As a city with more than 11 million inhabitants, the distribution of emergency services and public hospitals is also heterogeneous, with scarcity in peripheral zones. That heterogeneity of resources also involves the quality of the medical care provided. The possibility of a standard care with fast transfer after thrombolysis and a tertiary backing system for ECG interpretation, catheterization and advanced support could improve this setting. In a project initiated in 2010, the São Paulo Municipal Health Secretariat, the Federal University of Sao Paulo/Paulista School of Medicine, the Emergency Mobile Health Care Service arranged a planed system of thrombolysis at peripheral hospitals or at the ambulances with immediate transfer to a unique tertiary center for early angiography and angioplasty of the culprit artery. The protocol uses recommendations of Brazilian and international guidelines, and is the same adopted for the management of ST elevation myocardial infarction at Paulista School of Medicine regarding the indications for thrombolytic agents, primary and rescue percutaneous transluminal coronary angioplasty (PTCA), and pharmacoinvasive therapy. The hypothesis of this study is that a network to provide the best care for patients with ST elevation myocardial infarction will reduce mortality rates. The main purpose of this registry is to provide demographics, metrics and results of this experience, maintaining complete records of clinical, laboratory and coronary angiography data of all patients allowing short-term outcome analysis of various variables in a large population. Additionally, follow-up outcomes will be provide in a sub-group of patients keeping their health care at the University or able to be tracked. All clinical endpoints of main interest will be assessed as single or composite endpoints for evaluation at different time intervals.
