Filter by:The goal of this randomized controlled trial is to determine the effects of aerobic interval training on levels of tiredness and functional performance in post-angioplasty patients. The main question it aims to answer is: Does aerobic interval training reduce fatigue and improve functional performance compared to medication alone in post-angioplasty patients? Participants will: Be randomly assigned to either the control group (medication) or the experimental group (medication + aerobic interval training) Perform aerobic interval training for 30 minutes, three times a week, for six weeks (experimental group only) Complete pre and post-intervention assessments using the fatigue severity scale, the 6-minute walk test, and the one minute sit to stand test Researchers will compare the two groups to see if aerobic interval training leads to significant improvements in fatigue levels and functional performance.
Quantitative flow reserve (QFR), derived from coronary angiography, has shown high accuracy in detecting significant lesions. Ultrasonic flow ratio (UFR), a new development from IVUS, integrates physiological estimation with intravascular imaging. Although both QFR and UFR are effective, there's no conclusive evidence favoring one over the other. The study aims to compare UFR and QFR's diagnostic performance against the conventional FFR standard in detecting significant coronary lesions.
In this analytical prospective study 498 patients over 40 years with any cardiovascular symptoms and without pre-established coronary artery disease ( CAD) were enrolled. Patients underwent CT scans to measure coronary artery calcium score (CACS), and total calcium scores were recorded. Then, conventional coronary angiography was performed for all the participants as the gold standard for diagnosing CAD (defined as at least one stenotic coronary artery with ≥ 50%). Framingham risk score (FRS) was also estimated for all the patients
Patients scheduled for elective coronary angiography due to chronic coronary syndrome are recruited at admission to hospital before the coronary anatomy is known. Immediately after coronary angiography measures thermo-dilution derived flow indices are obtained in the left left anterior descending artery (LAD). The patients are followed through telephone-calls and medical records at 1 and 2 years after inclusion and at completion of the study. The hypothesis is that elevated index of microcirculatory resistance (IMR),(>25) is associated with all-cause death, myocardial infarction (MI) and hospitalization due to congestive heart failure (CHF). The primary analysis is the relationship between IMR and the composite outcome all-cause death, MI and hospitalization due to CHF.
This hospital-based registry study at Istanbul Medipol University Hospital focuses on documenting and analyzing the clinical and demographic characteristics, procedural-related aspects, and both short and long-term outcomes of patients undergoing left main coronary artery percutaneous coronary intervention (PCI). The study aims to identify predictors for adverse clinical outcomes in patients treated for left main coronary artery disease.
In this retrospective study from professor Kojuri clinic registry, total number of 1017 patients with first angiography were included and all data were recorded from registry. Insulin resistance was calculated using laboratory data
The purpose of the study is to implement a multimodal lifestyle intervention over 3 months in individuals ≥ 60 years of age with coronary heart disease and to examine the adherence to this intervention program. The intervention focus on three main themes: physical activity, healthy nutrition and, if necessary, smoking. The framework is formed by a psychological component: views on ageing.
To validate and investigate the efficacy of comprehensive functional assessments for the diagnostic and prognostic value in NOCAD.
The goal of this study is to compare the efficacy of a new harvesting technique for an arterial conduit(LIMA - Left Internal Mammary artery) in patients undergoing Coronary artery bypass grafting. The researcher will compare the 1. Time taken to harvest the artery 2. Flow of blood between the two techniques
The current study evaluated the diagnostic performance for myocardial ischemia of on-site automatic CCTA-derived FFR (CT-FFR) using a commercially available workstation as compared with invasive FFR as a reference. The diagnostic performance of CT-FFR was compared to that of CCTA diameter stenosis.
