Participation in outpatient cardiac rehabilitation (CR) decreases morbidity and mortality for patients hospitalized with myocardial infarction, coronary bypass surgery or percutaneous revascularization. Unfortunately, only 10-35% of patients for whom CR is indicated choose to participate. Medicaid coverage and similar state-supported insurance are robust predictors of CR non-participation. There is growing recognition of the need to increase CR among patients with this form of insurance and other economically disadvantaged patients, but there are no evidence-based interventions available for doing so. In the present study we are examining the efficacy of using financial incentives for increasing CR participation among Medicaid patients. Financial incentives have been highly effective in altering other health behaviors among disadvantaged populations (e.g., smoking during pregnancy, weight loss). For this study are randomizing 130 CR-eligible Medicaid enrollees to a treatment condition where they receive financial incentives contingent on initiation of and continued attendance at CR sessions or to a "usual-care" condition where they will not receive these incentives. Treatment conditions will be compared on attendance at CR and end-of-intervention improvements in fitness, decision making and health-related quality of life. Cost effectiveness of the treatment conditions will also be examined by comparing the costs of the incentive intervention and usual care conditions with their effects on increasing CR initiation and adherence. Should this intervention be efficacious and cost-effective, it has the potential to substantially increase CR participation and significantly improve health outcomes among low-income cardiac patients.
Exercise therapy increase functional capacity improving the morbidity and mortality of patients with cardiovascular disease. Moderate continuous training is the best established training modality for this patients. However, a body of evidence has begun to emerge demonstrating that high intensity interval training obtained better results in terms of morbidity and mortality. The purpose of this randomized clinical trial was to determine the effect of two types of exercise training: moderate continuous training vs high interval training on functional capacity and quality of life as well as verify the safety in its application. We included 72 patients with coronary artery disease by assigning one of the training modality for 8 weeks. We analyzed cyclo-ergo-spirometry data, aspect related to quality of life as well as a record of adverse events.
The purpose of this study is to develop a tai-chi based exercise program designed for patients who recently had a heart attack and do not wish, or are unable, to attend traditional cardiac rehabilitation.
Coronary heart disease (CHD) is the leading cause of death worldwide. The disease is characterized by a high mortality rate (about 40%) and a course continuously altered by lifestyle, gene polymorphisms and therapeutic treatment. Fasting concentration of blood lipids and lipoproteins only partially express the complex relation between dyslipidemia and CHD. Following the indication stated nearly 40 years ago by Zilversmit, there is now accumulating evidence that postprandial lipemia plays an important role in the atherogenic process [ref Kolovou], particularly that most hours of the day are spent in the postprandial state. Furthermore, the increases in blood glucose and triglycerides (TGs) following meals stimulate oxidative stress, impair endothelial function, and rises the inflammatory factors that lead to atherosclerosis. Previous studies reported on postprandial lipemia in subjects with obesity, metabolic syndrome, diabetes mellitus, elderly, patients with CHD and others. However, currently the estimation of cardiovascular disease risk is based on fasting blood values of triglycerides (TGs) and inflammatory markers. The effect of postprandial atherogenic factors on the initiation and progression of atherosclerosis is actually not known.The Hellenic Postprandial Lipemia Study (HPLS) was designed to study the consequences of postprandial lipemia in CRP as inflammatory marker in high-risk adults. Furthermore, the HPLS study will investigate whether hypolipidemic, hypoglycemic or antihypertensive medication may lessen the exaggerated postprandial lipemia as well as the rest abnormal postprandial metabolism. Finally, the HPLS study is intending to evaluate the influence of gene polymorphisms involved in lipid and glucose metabolism on postprandial lipemia and cardiovascular outcomes.
The present study aims is to investigate: 1. whether patients suffering from acute resp. chronic ischemic heart disease show higher levels for cadmium (Cd), lead (Pb) and mercury (Hg) than local and international reference levels suggest; 2. the correlation between severity of coronary artery disease and angiogenic and angiostatic factors (endostatin-ES, angiostatin-AS, VEGF-vascular endothelial growth factor, osteopontin-OPN) The patient population consists of about 270 female and male patients suffering either acute or chronic ischemic heart disease (AIHD:ICD-10 I21; CIHD: ICD-10 I25). 3. whether patients suffering CAD and valve calcification (mitral annulus, aortic valve) show higher levels of endostatin, angiostatin, osteopontin and VEGF compared to patients with CAD but without valve (annulus) calcification The measurement of cadmium (urine), lead, mercury, zinc, endostatin, angiostatin, VEGF (serum) and osteopontin (plasma) in patients with angiographically verified coronary artery disease are in the fore. Furthermore, basic laboratory diagnostics as well as data from coronary angiography and echocardiography will be collected. Additionally, the investigators will inquire heavy metal exposition during life by an interview. Recruitment will be done during the in-patient stay at the General Hospital of Vienna, Medical University of Vienna.
This study is a prospective randomized trial to evaluate and compare the quantitative and qualitative characteristics of neointimal formation between high and low efficacy statin treatment after drug eluting stent (DES) implantation, in patients with homogeneous or heterogeneous neointimal pattern accessed by Optical Coherence Tomography (OCT). The investigators postulate that high efficacy statin could have superior effect on modification of neointimal pattern, compared with lower efficacy statin. Our main hypothesis is that Atorvastatin 40mg, high efficacy statin might have superior effect on modification of neointimal pattern evaluated by serially followed OCT, compared with pravastatin 20mg in patients with DES implantation.
Trimetazidine (1-[2,3,4-trimethoxybenzyl] piperazine dihydrochloride) is a clinically effective antianginal agent. Despite these clinical successes, the understanding of trimetazidine's mechanism of action remains incomplete, particularly influence of trimetazidine on mitochondrial function in isolated human cardiomyocytes. The investigators will perform this study to seek possible differences in mitochondrial respiration related to standard preoperative enrolled trimetazidine therapy.
Bioresorbable polymer drug eluting stents (DES) are an indisputable improvement over first-generation DES with promising results on long-term adverse events. But the thicker polymer and/or strut may hinder its deliverability. Complex procedures challenge stent deliverability and stent delivery failure impacts clinical prognosis. This registry aimed to assess the immediate performance of the third-generation Synergy everolimus-eluting stent (sEES) and its 12-month clinical follow-up in an all-comer population.
Background About 2/3 patients of coronary heart disease (CHD) are complicated with disorder of carbohydrate metabolism which results in hyperglycemia and subsequent abnormality of coagulation system and inflammation. These patients have serious coronary artery pathology, multiple complications and poor prognosis. Platelets and lymphocytes play important roles in the occurrence and progression of atherosclerosis. The platelet/lymphocyte rate (PLR) is one simple hematological index. Previous studies confirmed that PLR could predict the long-term mortality of non-ST elevated myocardial infarction (NSTEMI). If simple hematological index could predict the prognosis of such kind of patients, it will provide new thought for early diagnosis and treatment in future. Therefore, the present study try to investigate if PLR could predict the poor prognosis of CHD patients complicated with impaired glucose tolerance (IGT) through calculating PLR. Methods/design The present study is performed with strategy of an observational and prospective single-centre cohort. These patients are recruited from August 2013 to August 2014, according to the inclusion criteria of CHD complicated with IGT. CHD is confirmed with coronary angiography while IGT is determined according to the WHO criteria (1999). Routine blood test and serum glucose data of patients are acquired before hospitalization and surgery. According to the median of PLR after admission, the patients are divided into 3 groups. The patients are followed up for half, 1 and 3 years, respectively. The major clinical endpoint is mortality. The minor clinical endpoint indices are the correlations of PLR with MACE (including mortality, recurrent rate of infarction and reperfusion rate of target vessels), recurrent infarction, re-perfusion rate of target vessel, intra-stand thrombogenesis, stroke and acute onset of heart failure. The correlations are analyzed with receiver operating characteristics (ROC) survival curve and Kaplan-Meier survival analysis to find optimal prognosis index. Summary Through regression analysis of long-term follow-up of patients, it is expected to find optimal predicting index of prognosis. While judging whether PLR is effective, other possible factors for new predictor are sought in order to provide help for future study.
