Filter by:Specific aim 1a will test the hypothesis that diabetic patients with 2-2 haptoglobin genotype have higher indices of postoperative myocardial injury (creatine kinase MB isoenzyme , Troponin I ) and renal injury (as indicated by elevated creatinine, cytostatin C and glomerular filtration rate). Of note, significantly elevated levels (>5 times the upper normal limit) of creatine kinase MB isoenzyme and troponins postoperatively have been associated with postoperative myocardial ischemia/infarction and are a predictor of short-term and long-term mortality after cardiac surgery. Specific aim 1b will evaluate preoperative and postoperative indices of oxidative stress (such as isoprostane f2 alpha and malondialdehyde) and will evaluate whether patients with type 2-2 haptoglobin express increased oxidative stress. The investigators will also try to correlate whether patients with increased oxidative stress are those with elevated indices of myocardial and/or renal injury Specific aim 1c will try to evaluate whether patients with type 2-2 haptoglobin also have increased levels of inflammatory indices (C-reactive protein,[interleukin] IL-1, IL-2, IL-6, TNF[tumor necrosis factor]) and try to correlate the findings with postoperative myocardial and or renal injury. The incidence of atrial fibrillation after coronary artery bypass graft ranges from 19% to 27%. The investigators will also look at any correlation of the type 2-2 haptoglobin and the incidence of post-operative atrial fibrillation.
In this observational study investigators examine the presence of circulatory oscillations in blood pressure, heart rate, and doppler laser flow before and after planned cardiac surgery.
Coronary revascularization improves survival for patients with coronary artery disease. However,many patients are left with poor physical and mental health. Traditional cardiac rehabilitation involves moderate intensity continuous exercise (MICE). Alternatives to traditional cardiac rehabilitation programming may however provide superior understudied benefits to patients with poor physical and mental health. Nordic walking (NW) and high-intensity interval training (HIIT) are two examples of alternative programs for cardiac rehabilitation, which may provide superior physical and mental health benefits when compared to traditional MICE. The main purpose of this project is, therefore, to determine the short and long term physical and mental health benefits of alternative cardiac rehabilitation modalities, including NW and HIIT on exercise capacity, quality of life and depression after a 12-week program.
Coronary artery disease is a common medical disease in many populations. The pathogenesis of this disease is very complex. Surgery is one of the treatment choices. Assessing the risk factors will improve the surgical outcome. In this study some biochemical parameters were evaluated to find out the relationship between these parameters (electrolytes and albumin vs)
The objective of this study is to carefully monitor all patients undergoing Computed Tomographic Perfusion (CTP) at Lancaster General Hospital for safety, and determine the efficiency of the CTP procedure in a community setting.
The study will compare clinical outcomes between complete revascularization during hospitalization for ST elevation myocardial infarction (STEMI) and intervention after 30 days and intervention based on outpatient non-invasive ischemia testing in patients with multivessel coronary artery disease (MVD) presenting with first ever ST elevation myocardial infarction.
The sample of this randomized controlled trial was obtained in the Cardiovascular Prevention and Rehabilitation Unit, of the Hospital Centre of Porto, Santo Antonio General Hospital. The target population was individuals who have completed the training phase of cardiovascular rehabilitation program, volunteers and referenced by the responsible for the service. This study has as main objective to analyze the influence of a specific exercise program, maintenance phase of cardiovascular rehabilitation , in home care context, for a period of 6 months, using a virtual format (computer and Kinect) or a conventional format (paper manual) in subjects with coronary artery disease. It was intended to analyze the immediate effect of exercise program on body composition and food consumption patterns, functional muscle strength of lower limb, level of physical activity: total volume of activity as well as the profile of this intensity, kyphotic index, balance, cognitive and executive function, as well as in the quality of life. The aim is also to examine the effects, approximately 3 months after the end of the exercise program, in the lipid profile, the level of physical activity: total volume of activity as well as the profile of this intensity and cardiovascular fitness: maximum double product ; metabolic equivalents; and proof and recovery time. The individuals were distributed at random, every 3 individuals, using the capabilities of Microsoft Excel 2010 RANDBETWEEN command, by three groups: the experimental group 1- a cardiovascular rehabilitation program, in home care context, using a computer and Kinect, virtual format, the experimental group 2- in cardiovascular rehabilitation program, in home care context, using a paper-based manual, conventional format, and control group-only subject to education for cardiovascular risk factors. The program defined 3 training sessions per week. The rehabilitation program was oriented by the guidelines for exercise prescription. Participants perform the a program of specific exercises independently and individually, with remote supervision, using communication (phone, email, etc.) and a routine scheduled individual meetings.
This will be a single-center, randomized, open-label, active-controlled, parallel-group study to investigate the platelet inhibition of Ticagrelor versus Clopidogrel with acetylsalicylic acid (ASA) as background therapy in approximate 40 patients with stable coronary artery disease (SCAD) and type 2 diabetes mellitus (DM) after recent successful elective percutaneous coronary intervention (PCI) by evaluation of the P2Y12 reaction unit (PRU) by VerifyNow P2Y12 assay at 2-4 hours after the first study drug dose on treatment day 15±2.
This is a prospective, non-randomized, single center clinical trial to assess neointimal coverage on the stent or scaffold strut and apposition of SYNERGY™ and ABSORB in minimum of 12 eligible human subject at 4 month and 12 month after stent or scaffold implantation using OCT and CAS
Prediabetes is a disorder of glucose metabolism that reflects the natural history of progression from normoglycaemia to type 2 diabetes mellitus. Patients with prediabetes have impaired glucose regulation caused by insulin resistance (IR). IR in patients undergoing percutaneous coronary intervention (PCI) is associated with coronary artery remodeling and coronary plaque vulnerability by intravascular ultrasound (IVUS) analysis. In stent restenosis after bare metal and drug-eluting stent implantation more frequently is observed in patients with high fasting-insulin levels and IR. Although IR has a significant role in the progression of atherosclerosis in prediabetic patients, the importance of managing prediabetes is often under-appreciated by clinicians. To date, no pharmacological treatment has been officially approved for prediabetes. According to American Diabetes Association recommendations, metformin is the only drug that could be considered in the treatment of prediabetic patients with a high risk of developing diabetes. Metformin is a safe and inexpensive glucose lowering drug that attenuates mortality and future cardiovascular events in patients with type 2 diabetes as well as the progression of atherosclerosis in non-diabetic animal models. This study was designed to analyze coronary plaque characteristics by iMAP IVUS in patients with and without prediabetes undergoing PCI and to evaluate the impact of metformin treatment on coronary plaque characteristics in prediabetic patients at 24 month follow up. The study hypothesis is that more pronounced coronary atherosclerosis progression as well as in-stent neointimal hyperplasia will be observed in patients with prediabetes. Metformin treatment attenuates the progression of atherosclerosis in patients with prediabetes.
