Filter by:Background: Family members (spouses, siblings, offspring) of patients with coronary heart disease (CHD) may themselves be at increased risk for developing CHD for genetic, biochemical and/or behavioural reasons. Targeted approaches aimed at family members of those with established CHD may be a cost-effective way to identify high-risk persons and link them to effective risk factor modification. During pilot testing we found 29% of family members of patients recently hospitalized at our institution had ≥ 3 CHD risk factors. Encouragingly, they indicated high levels of "readiness" to change underlying risk behaviours such as cigarette smoking and physical inactivity. We have developed a 12-week family heart health program featuring a personal plan for achieving risk factor goals and weekly contact with a heart health educator. This intervention needs to be fully tested. Research Aims: In this study, we will: 1. Compare the effects of a targeted family heart health (FHH) screening, counselling and follow-up program versus usual care (UC) for reducing participants total cholesterol/high density lipoprotein (TC/HDL) ratio 52 weeks after program entry, in family members of patients recently hospitalized with CHD; 2. Compare the effects of the FHH program versus UC on modifiable components comprising the Framingham score, including: smoking status; systolic blood pressure; total cholesterol; and high density lipoprotein cholesterol; 3. Compare the effects of the FHH program versus UC on: lifestyle-related factors (dietary patterns, leisure time exercise, body composition); medication use (anti-lipemic medications, anti-hypertensive medications, pharmacotherapies for smoking cessation); and use of healthcare resources (physician visits, hospitalization days, number of laboratory and diagnostic tests and procedures).
To determine if 16-64 slice multidetector CT (MDCT) can replace the invasive procedure in patients scheduled for coronary angiography in order to exclude the presence of CAD
A cholesterol/lipid profile screening project of high risk patients with hyperlipidaemia (secondary prevention) who already receive cholesterol-lowering therapy. Lipid profile and rate of patients who are treated to target (which is <100mg/dl for patients with high risk and <70mg/dl for patients at very high risk) are screened (office-based specialists). The doctors therapy decisions after the screening and possible reasons for these decisions will be documented. Our aim is to evaluate dosing habits, to evaluate how many patients are treated to their LDL-C target and to underline the importance of treating patients to their cholesterol targets.

The purpose of this study is to determine whether treatment of Rosuvastatin (CRESTOR™) or Simvastatin given as monotherapy or given in combination with Ezetimibe, will lower the Low Density Lipoprotein Cholesterol (LDL-C) in patients with Hypercholesterolaemia and Coronary Heart Disease (CHD) or a CHD Risk Equivalent, Atherosclerosis or a 10-year CHD Risk of >20%
The PREDICT study is to develop and validate a diagnostic blood ASGES (age, sex, gene expression score) or Corus CAD for atherosclerotic coronary artery disease (CAD). The Corus CAD (Age/Sex/Gene Expression score - ASGES) will use quantitative real-time PCR (RT-PCR) to quantify the expression of multiple genes from circulating peripheral blood cells to assess the presence of clinically significant CAD in a patient.
Randomized prospective study to compare the efficiency and safety of EPC-capture stents (Genous, OrbusNeich) and bare metal stents with concommitant high dose atorvastatin in reduction of neointimal formation assessed by quantitative coronary angiography and IVUS. Also the association between the function (transcriptional activity, migration) and number of circulating EPCs and angiographic outcomes will be investigated.
A Randomized Comparison of a Titanium-Nitride-Oxide Coated Stent (Helistent Titan2, Hexacath) With a Zotarolimus-Eluting Stent (EndeavorTm, Medtronic) for Percutaneous Coronary Intervention
Effects of statin and ezetimibe association on kinetics of artificial chylomicrons in men with stable coronary heart disease (CHD). Background: The rate (kinetics) of chylomicrons removal from circulation have been correlated with the incidence and severity of atherosclerotic lesions; a number of studies demonstrated lower plasmatic clearance of chylomicrons in patients with CHD compared to patients without this condition. It was also demonstrated a correlation among LDL-C levels and removal of chylomicrons remnants by a technique employing artificial chylomicrons. The investigators also know that higher doses of more potent statins are more effective in chylomicrons removal than lower doses or less potent statins; nevertheless, the effect of the isolated use of statin has not been completely studied up to now. Study design: The investigators propose to study 26 outpatients volunteers with chronic CHD, followed at the Heart Institute - INCOR - of the School of Medicine, University of São Paulo. Following a period of six weeks of washout from any cholesterol reducer, the kinetics of chylomicrons removal by a technique of emulsion of radiolabeled artificial chylomicrons will be evaluated. Lipid fractions, hepatic enzymes and CK will be measured. Initially patients will be randomly allocated to receive simvastatin 20 mg /day (n= 13) or ezetimibe 10 mg/day (n=13) for six weeks. At the end of this period, kinetics of chylomicrons removal and laboratorial measurements will be repeated (Period 1). In the next period (Period 2) patients will receive simvastatin 20 mg/ ezetimibe 10 mg (n=13) or simvastatin 80 mg (n=13) for additional six weeks; at the end of this period, the evaluations will be repeated (third and last evaluation). The aim of this study is to further understand chylomicrons metabolism in patients with chronic coronary disease receiving cholesterol reducers at different dosage regimes.
Patients with underlying cardiovascular disease are at high risk of perioperative cardiovascular events and death. Hemodynamic variables are controlled by the autonomic nervous system reflected by Heart Rate Variability. To investigate whether differences of HRV parameters predict perioperative cardiovascular events.
