Active clinical trials for "Angina Pectoris"

To perform a randomized comparison between the Cypher Select+ stent and the Nobori stent in the treatment of unselected patients with ischaemic heart disease.

Female patients presenting with persistent chest pain despite no obstructive coronary artery disease have impaired prognosis. Stress tests are often positive or inconclusive. As much as 20% of women with chest pain and minimal angiographic CAD have evidence of myocardial ischemia, suggesting impaired coronary microcirculation. The index of microvascular resistance (IMR) is a method for indirectly investigating microvascular function in the cardiac catheterization laboratory. 66 female patients, age 30-70 years, with chest pain and "normal" or near normal coronary angiograms will be included. After coronary physiologic evaluation, patients will be randomized in a double blind study to rosuvastatin 20 mg/day or matching placebo tablets for altogether 6 months. The investigators hypothesize that: A substantial number of women with chest pain and normal or minimal pathology on angiograms have microvascular dysfunction defined by a raised IMR. Statins, based on its pleiotropic action will improve endothelial function and thereby IMR.

Low intensity shockwaves have been proven in animal studies to induce local growth of new blood vessels from existing ones. The hypothesis of this study is that shockwave therapy could improve the symptoms of patients with refractory angina not amenable to revascularization with angioplasty or bypass surgery.

In coronary artery bypass grafting, saphenous veins are widely used as a composite grafts that are Y-anastomosed to in-situ left internal thoracic artery. Based on our observation that remodeling of saphenous vein graft differs between those harvested from upper leg vein and lower leg, this study aims to compare histologic and immunohistochemical findings between saphenous vein grafts harvested from upper leg and lower leg.

The purpose of this study is to evaluate differences in the pharmacokinetics and pharmacodynamics of ticagrelor and its active metabolite between patients who received ticagrelor and morphine followed by metoclopramide versus patients treated with ticagrelor and morphine alone for unstable angina pectoris.

Study aim : To compare a novel strategy of lesion preparation with noncompliant balloons before implantation of BVS. Hypothesis: Predilatation with non-compliant balloons could facilitate optimal deployment of BVS. By achieving good scaffold apposition a need for post-dilatation could be significantly reduced. This is expected to result in better short- and long-term outcomes.

This is a double-blind, randomized, placebo-controlled, and parallel study. The study is comprised of three main phases: a single-blind placebo run-in qualifying phase lasting about 14 days, a double-blind treatment phase of 12 weeks, and a 2-week follow-up phase. Approximately 18 patients will be enrolled and randomly assigned to receive placebo or 1,000 mg of extended-release Ranolazine twice-daily for 12 weeks to reach 14 evaluable patients at the end of the study.

60 elective patients for CABG will be included to receive either standard hyperkalemic cardioplegia (St.Thomas Hospital Solution No I) or cardioplegia where supranormal potassium is replaced with 1.2 mM adenosine. Hypothesis as follows: 1. Adenosine instead of supranormal potassium in the cardioplegic solution give satisfactory cardiac arrest. 2. Adenosine instead of supranormal potassium in the cardioplegic solution gives equal cardioprotection. The patients will be followed with PiCCO-catheter to monitor cardiac function and repetitive blood samples to measure release of cardiac enzymes.

Low intensity shockwaves have been proven in animal studies to induce local growth of new blood vessels from existing ones. The hypothesis of this study is that shockwave therapy could improve the symptoms of patients with refractory angina not amenable to revascularization with angioplasty or bypass surgery.

The study investigates whether endurance training breathing 100% oxygen gives a additional improvement of maximal oxygen uptake in stable Angina Pectoris patients, compared to training without extra oxygen supplementation. In addition work economy, stroke volume and cardiac perfusion is measured. The hypothesis of the study is that increased oxygenation of the air increases performance, stroke volume, work economy and cardiac perfusion.
