The research project includes two components that assess exercise physiology parameters, cerebrovascular reserve, cognitive functions and cardiac function in coronary heart disease patients at rest, during an acute exercise, and after two different periodized training programs.
Over a 12-month period, patients admitted with acute coronary disease to the cardiovascular care unit at the Jewish General Hospital (JGH), an academic tertiary care referral center in Montreal, Quebec, will be approached to refer first-degree relatives and/or household members age 18 years or older to an outpatient cardiovascular (CV) risk factor screening and treatment program. Relatives and household members will undergo a focused history, physical, and CV risk factor assessment and will receive evidence-based guideline-recommended treatment as indicated. Participants will be referred to nutritionists, smoking cessation programs, and to other allied healthcare professionals as needed. A follow-up visit at 6-months will assess treatment adherence and improvement in CV risk factors. All family and/or household members including the index patient will be encouraged to attend all healthcare visits together. The effectiveness of the screening strategy will be measured by the total number of participants identified as intermediate or high modified Framingham 10-year risk of cardiovascular disease. The effectiveness of the primary prevention intervention will be measured by the change in percentage of the mean modified Framingham 10-year risk score for participants between the initial visit and 6-month follow-up. The value of the referral, screening, and treatment program, as well as participant engagement and satisfaction will also be systematically evaluated.
Cardiovascular disease (CVD) is highly prevalent in women resulting in 398,086 deaths annually. Even as women participate in traditional CR programs, data specificity and subsequent research have yet to emerge in a meaningful way so that women-centered CR can be better customized and their outcomes properly assessed. Aerobic fitness is a powerful predictor of prognosis in individuals with CVD yet there is evidence that women do not improve their peak VO2 as much as men during CR. We have designed a training program for women based upon past research with a goal of optimizing their training potential in CR. This program combines the utilization of a training technique termed high intensity interval training along with specific strength training exercises of the upper legs. We hypothesize that women, irrespective of age, would be capable of high intensity interval training to improve peak aerobic capacity in the CR setting. Furthermore, since women often have a deficit of thigh strength entering CR, and thigh strength correlates with endurance walking,strength training will also be included. The purpose of this study is to examine the value of high intensity interval training and strength training to maximize aerobic training response in CR for women. This may contribute to establishing specific protocols and training guidelines for future program design for women in CR. Since a set of comprehensive CR guidelines pertaining to women is lacking, it is hoped that the results of this study will help us develop exercise protocols and regimen to better structure and modulate CR programs for optimal benefit to women.
The purpose of the study is to assess the feasibility of Cardiac Shock Wave Treatment in patients with anginal chest pain and evidence of abnormal myocardial perfusion under stress in the absence of significant stenoses of the epicardial coronary arteries.
Background: Despite preoperative screening, technical improvements and increased patient monitoring, perioperative myocardial infarction (PMI) remains the first cause of morbidity and mortality within 30 days after surgery. Moreover, the available evidence indicates worrying rise of risk in postoperative patients with only elevated troponins reflecting cardiac injury, but without a conventional clinical diagnosis of myocardial infarction according to current definition. Worldwide, annually approximately 300 million adults undergo major non cardiac surgery and 10 million of them are estimated to suffer a myocardial injury after non-cardiac surgery (MINS), defined as a prognostically relevant increase of a troponin T peak of 0.03 ng/ml or greater. Many of the patients with MINS does not fulfill the universal definition of myocardial infarction, rarely experience ischemic symptoms and their prognosis is very poor (1 out of 10 die at 30 days).Troponin levels needed to be monitored in order to MINS diagnose and high sensitive cardiac troponin T assays are currently the most frequently used. Methods: Patients with high cardiovascular risk undergoing major non-cardiac surgery will be selected from the daily surgical program during a two years period Three determinations of hs-cTnT for each patient will be obtained. The proportion of patients with MINS and pre- and post-operative thresholds of hs-cTnT that would be prognostically relevant will be determined. The cost-effectiveness analysis of hs-cTnT monitoring compared with usual care will be undertaken. Finally using computed tomography angiography (CTA) and cardiac magnetic resonance imaging (MRI) pathophysiology of MINS will be determined, whether is due to plaque rupture, supply-demand mismatch, non-ischemic cardiac cause or non-cardiac cause. Discussion: The study will evaluate the feasibility and impact of implementing the hs-cTnT monitoring program in the Hospital de la Santa Creu i Sant Pau of Barcelona, as well as its cost-effectiveness. Moreover, this is the first study which will determine pre and postoperative thresholds of hs-cTnT and with minimally invasive diagnostic tools will evaluate potential mechanisms involved in perioperative ischemic events.
This study investigates the effectiveness of a Finnish Tulppa outpatient rehabilitation program. Tulppa is a group-based secondary prevention program for patients with vascular diseases. The program is developed by the Finnish Heart Association. The intervention is implemented at the local primary health care centers in 12 health districts in Finland. A longitudinal controlled study is used to investigate the effects of the intervention on participants' level of cardiovascular risk factors (e.g. lipids, blood pressure, body mass index), functional capacity (e.g. 6 minute walk test), life style as well as psychosocial factors (e.g. smoking, diet, physical activity, health-related quality of life and depression). The data will be collected at baseline (i.e. before the intervention), and 6 and 12 months after the intervention started. The participants (n = 300) are patients diagnosed with coronary heart disease. The study group (n = 150) is recruited from participants of Tulppa rehabilitation in three health care districts (Pirkanmaa, South Karelia, Päijät-Häme). The control group (n = 150) is recruited from two health care districts (Turku and Hyvinkää) that do not provide Tulppa rehabilitation.
To date there is very little PD and pharmacokinetic (PK) data on the ticagrelor 60 mg bid dosing regimen. In particular, there is no prospective PK/PD study on this dosing regimen in patients with DM who are known to have impaired response to clopidogrel therapy. Since DM patients frequently require elective PCI due to chronic progression of CAD (and not solely because of an acute thrombotic complication), and clopidogrel remains the guideline recommended P2Y12 inhibiting therapy for these patients, understanding the PD effects of the ticagrelor 60 mg bid regimen in this setting is an unmet clinical need. This is also in light of the ongoing THEMIS trial which is specifically evaluating the impact of the ticagrelor 60 mg bid dosing regimen in type 2 DM patients without a prior major CV event.
The present study is aimed to investigate whether oral L-arginine supplementation reduces the adverse cardiovascular effects of exposure to traffic-related air pollution among a group of non-smoking adults with elevated blood pressure.
