Filter by:Aim: To investigate and compare women's and men's expectations before investigation and treatment of suspected coronary artery disease and to examine how these expectations are met. Do women and men, of different ages, have the same expectations for the evaluation and treatment of stable coronary artery disease and are their expectations met in a equal degree? Are there differences in expectations and the fulfilment of these according to age and other clinical history variables? Do the findings in the specially developed questionnaire designed to gather patients' expectations to the outcome on quality of life and degree of angina pectoris relate to their appearance in the designated forms? Is there a relationship between NTproBNP - levels, as a measure of cardiac workload, and expectations and the fulfilment of these as well as the quality of life and degree of angina pectoris? Method: Patients will be asked to participate in the study, in the context of medical consultation before coronary angiography by a physician and / or a study nurse. This occurs during an outpatient visit at the cardiac clinic at the respective centre. Included are all patients planned for elective coronary angiography before possible revascularization during a eight month period regardless of diagnosis. Including are four hospitals in the region of Västra Götaland.
Aerobic interval training is shown to be superior in increasing oxygen uptake in both healthy and patients with coronary artery disease (CAD), compared to moderate continuous training. However, in cardiac rehabilitation exercise groups, exercise intensity is usually controlled with perceived exertion (Borg scale). The investigators will investigate degree of agreement between target heart rate and perceived exertion during interval training in cardiac rehabilitation.
Women who have regular menstrual cycles have a lower risk of heart disease than men of the same age or women who no longer have menstrual cycles. The purpose of this study is to help determine why the menstrual cycle causes a lower risk of heart disease. The investigators believe that the hormones (estradiol and progesterone) produced during the menstrual cycle, as well as the normal processes occurring in the follicle and corpus luteum (transformed follicle), change levels of "good" and "bad" cholesterol in the blood-stream. These levels of good and bad cholesterol are an important risk factor for heart disease. Therefore, our goal is to determine what effects each of these factors (estradiol, progesterone, follicle, corpus luteum) have on the levels of good and bad cholesterol in the woman's bloodstream. As many women take birth control pills, which contain synthetic forms of estradiol and progesterone that block ovulation and development of a corpus luteum, the investigators also want to determine what effect one common type of birth control pill has on levels of good and bad cholesterol.
Dual antiplatelet therapy with Aspirin and Clopidogrel for at least one year is essential in patients following an acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) with drug eluting stent(s) implantation. Interindividual variability in platelet response to Clopidogrel has been reported, with several mechanisms (intrinsic high platelet reactivity [PR], variability of the drug metabolism, and various drug interactions) being implicated for high post-Clopidogrel treatment PR. The investigators aim to perform a prospective, single-center, investigator-initiated, randomized, study to compare platelet inhibition by Prasugrel 10 mg/day, Ticagrelor (90 mg twice daily) and high-dose 150 mg/day Clopidogrel in patients with High on-treatment platelet reactivity (HTPR) with standard dose of Clopidogrel. Patients with HTPR (defined as area under curve-AUC ≥ 450 or > 45 Unit) and with loss-of-function allele CYP2C19*2 will be enrolled in the study and will be randomized (Day 0) in a 1:1:1 ratio, to either Clopidogrel 150 mg a day or Prasugrel 10 mg a day or Ticagrelor (90 mg twice daily) until Day-15 and-30 post randomization.
The purpose of this study is to demonstrate improved vein graft patency rates at 12 months for endoscopically harvested saphenous vein grafts. The study will evaluate use modifications to existing techniques in vein graft handling during harvests. A secondary aim is to develop a standardized approach for harvesting, handling, and preparing vein grafts in the endoscopic approach.
The purpose of this study is to evaluate the safety and efficacy of Drug-Eluting Balloon first and then bare metal stent compared with drug-eluting stent for treatment of de novo lesions (DEB first).
The primary objective of this study is to evaluate safety and efficacy of the BIOTRONIK PRO-Kinetic coronary CoCr-stent in patients with single de novo lesions of native coronary arteries.
The purpose of this study is to assess the pharmacodynamic effect of ticagrelor in African American patients with stable coronary artery disease.
The purpose of this study is to assess the pharmacodynamic effect of ticagrelor in Hispanic patients with stable coronary artery disease.
To demonstrate that using continuous mechanical lung ventilatory support in combination with Positive End Expiratory Pressure (PEEP)during open heart surgery will improve lung function and decrease lung complications after surgery.
