Ischaemic PReconditioning In Non Cardiac surgEry

Myocardial IschemiaSurgery

Several randomized trials suggested a cardioprotective beneficial effect (eg reduction in cardiac troponin release) of remote ischemic preconditioning in cardiac surgery. Remote ischemic preconditioning by brief episodes of ischemia and reperfusion in a remote organ or vascular territory provides protection from injury by myocardial ischemia and reperfusion. In the translation of remote ischemic preconditioning from bench to bedside, the first proof of principle and small randomized controlled trials have shown a decreased release of myocardial biomarkers after aortic, congenital cardiac, adult valve and coronary artery by-pass graft surgery. This reduction in cardiac biomarkers release translated into better survival in a recent randomized trial performed in cardiac surgery. No clinical trial on remote ischemic preconditioning in non-cardiac surgery setting has been performed so far. The investigators study wants to test, for the first time, the hypothesis that remote ischaemic preconditioning is effective in reducing cardiac damage in high risk patients undergoing non-cardiac surgery. Remote ischaemic preconditioning will be achieved by inflation of a blood-pressure cuff to 200 mm Hg to the upper arm for 5 minutes, followed by 5 minutes reperfusion while the cuff will be deflated. General anesthesia will be induced and maintained without using propofol in both groups. Cardiac troponin will be used as marker of cardiac damage. If the results of a reduction in postoperative cardiac troponin release and perioperative cardiac ischaemic events will be confirmed in a non-cardiac surgery setting, the investigators could improve a strategy to prevent perioperative cardiac complication easy to apply, safe and low cost.

Stress Management in Patients With Coronary Artery Disease

StressPsychological

Introduction: Stress can cause hemodynamic and metabolic changes that contribute to endothelial dysfunction and there is a significant association between high stress and cardiovascular events. Objective: To evaluate the influence of stress management on endothelial function in patients undergoing percutaneous coronary intervention (PCI). Methods: Randomized, controlled, parallel, intention-to-treat clinical trial. Will be considered eligible patients who underwent percutaneous coronary intervention and who have high stress (above average for the Brazilian population) in the Perceived Stress Scale (PSS-10). Patients will be evaluated on PCI admission and stress management with cognitive behavioral techniques will be implemented one month after hospital discharge in the intervention group. Group sessions will be held between 6-9 people. There will be 4 1-hour meetings for 8 weeks. The primary outcome will be the difference in the variation of brachial artery flow-mediated dilatation (FMD) between the groups and at 3 months of baseline evaluation and at 6-month follow-up after the intervention and the secondary outcome will be the difference in the variation of the velocity of brachial artery. Pulse wave evaluated at the same time periods as DMF. Outcomes will be evaluated by Generalized Estimation Equations (GEE). Expected Results: In patients undergoing high-stress percutaneous coronary intervention, the use of cognitive behavioral techniques for stress management will improve endothelial function and vascular stiffness.

Personalized Activity Intervention in Rehabilitation After Cardiac Operations (the PACO Trial)

Coronary Artery DiseaseAortic Valve Stenosis1 more

The PACO trial is a randomized clinical trial conducted in Heart Centers of Kuopio and Turku university hospitals. The coronary artery disease, aortic valve stenosis and mitral valve insufficiency patients preparing for elective coronary artery bypass grafting (CABG), aortic valve replacement (AVR) or mitral valve repair (MVR) will be randomized to either intervention or control group. The specific operation groups (CABG, AVR and MVR) will be analyzed separately. The 7-day baseline measurements of sedentary behaviour (SB), physical activity (PA) and sleep will be conducted to the patients by using the RM42 accelerometer during the pre-operative month. After the cardiac procedure is completed and the patient is moved to post-operative ward, the control group patients will begin the standard post-operative rehabilitation program of the participating hospitals (activity guidance given by a physiotherapist). Patients in the intervention groups will follow the identical program but after discharge they will also receive personalized activity guidance through the combination of ExSed smart phone application, Suunto MoveSense accelerometer and cloud system during the first 90 days of post-operative rehabilitation. Weekly evolving daily goals to replace SB with PA (daily goals for steps, moderate PA, light PA and standing, and sitting time limit) will be designed for each patient of the intervention groups. A new daily step goal will be delivered from the cloud system to the patient's smart phone in the beginning of each week of the intervention. The daily step goal of the first intervention week is based on patient's walking distance assessed by a physiotherapist in post-operative ward. The following goals will be automatically evolved in the basis of patient's personal average step count of the previous week. The MoveSense accelerometer will measure accumulated levels of SB, PA and sleep, and transmit the data to user's ExSed application with Bluetooth. With information about accumulated levels of SB and PA, the application is able to guide the patient to accomplish the predefined activity goal. The guidance and motivation will be offered with pop-up notifications and histograms (columns are fulfilled according to patient's accumulated daily activity). The researches retain a remote access to the activity data of patients in the cloud system. The ExSed application will be connected to the cloud system with internet connection. In addition, the patients of the intervention groups will receive short video files (lasting from 1 to 3 minutes) containing exercise guidance from a physiotherapist specialized to cardiac operation patients. These videos are available on the ExSed application during the intervention. The physiotherapist will also contact each patient (by mobile phone) with structured contact form from 1 to 4 times in a month to make sure that the intervention is proceeding as designed.

Development of Novel Physiological CMR Methods in Health and Disease

Heart FailurePulmonary Hypertension2 more

Physiological cardiovascular stress test plays a crucial role in the assessment of patients with suspected heart disease. There are several methods of cardiac physiological stress tests and each of them offer varied insight into cardiac physiological adaptation: passive leg raise, intra-venous fluid challenge, pharmacological stressors and physical exercise stress test. Echocardiography, which is the mainstay for the non-invasive rest/stress assessment of the left ventricular (LV) haemodynamics has several limitations. Novel methods of CMR imaging allow to map intra-cardiac flow in three-dimension using novel flow acquisitions. These novel flow acquisitions are called four-dimensional flow CMR, where the fourth dimension is time. Additionally, traditional cine CMR imaging for functional assessment can now be done without breath-holds using advanced acceleration methods, allowing them to be used during exercise. A comprehensive understanding of functional-flow coupling at rest, during increased pre-load (fluid challenge) to the heart or during exercise, is lacking in the literature. There is an important need to validate these novel CMR methods for developing mechanistic insight into physiological cardiac adaptation to increased pre-load or to exercise in health and how it alters in heart disease.

Remote Ischemic Preconditioning on the Prognosis of Patients With Elective PCI Using Drug-coated...

Coronary Artery Disease

Drug-coated balloon is being used more and more widely for the advantage of intervention without implantation. But the balloon needs to be released long enough to be effective. Prolonged balloon dilation resulting in the cessation of blood flow in the distal vessels, especially large vessels, may result in severe ischemia in the patient. RIPC can enhance patients' tolerance to ischemic events, so we believe that RIPC application before the use of drug balloon for PCI can improve patients' ischemic symptoms, thus increasing the release time of drug balloon and improving the effect.

Effectiveness of TechCR Among CHD Patients

Coronary Heart Disease

During this ongoing pandemic, there is a crucial need for innovative approaches to deliver CR programmes other than frequent face-to-face sessions at the centre-based CR to reduce the number of times people come close in contact with others or gathering in large groups. This is a single setting, 2-arm parallel randomised clinical trial which aims to examine the effects of technology-assisted interventions in hybrid cardiac rehabilitation (TecHCR) among the coronary heart disease patients. Eligible participants will be randomly assigned into either intervention group (IG) or control group (CG) in 1:1 ratio using the computerised permuted blocks, alternating block sizes of 4 or 6. All participants will be followed up for three months and six months with data collection at baseline, (T0), three-month (T1) and six-month (T2) time points.
