Filter by:To study the hypothesis that treating patients with underlying diastolic dysfunction with oral Kuvan® (BH4, also known as tetrahydrobiopterin) in addition to current best practices will improve metabolic and echocardiographic diastolic function parameters.
Therefore, the purpose of this study is to compare the effectiveness of two exercise training programs for improving cardiorespiratory fitness: the ACE three-zone training model (i.e., threshold based training) versus the more common ACSM recommended relative percent method (i.e., %HRR). It is hypothesized that: 1. The ACE three-zone training model will elicit greater mean changes in cardiorespiratory fitness (as measured by VO2max) when compared to the relative percent method. 2. Participants in the ACE three-zone training model group will be more likely to have favorable VO2max responses; while comparatively, participants in the relative percent method group would be more likely to experience a VO2max nonresponse to exercise training.
Cardiovascular disease (CVD) is the leading cause of death globally and e-health educational programs have been proved to be effective support to CVD clients. However, most e-health programs lack personalization and this seldom results in exercise behavioral change. Considering the advantages of e-health programs, as well as the widespread internet use and the rising trend of younger patients having CVD in Hong Kong, we conducted a Randomized Controlled Trial (RCT) to investigate the effectiveness of a home-based interactive e-health educational intervention versus usual care for middle aged cardiac vascular (CV) patients on their total physical exercise, exercise adherence and quality of life.
This study will compose a national database of cardiovascular diseases' risk factors, concomitant diseases and the drug usage among the elderly patients in Turkey.
People infected with HIV are at risk for cardiovascular disease (CVD). This study will evaluate the use of pitavastatin to reduce the risk of CVD in adults infected with HIV who are on antiretroviral therapy (ART). The REPRIEVE trial consists of two parallel identical protocols: - REPRIEVE (A5332) is funded by the NHLBI, with additional infrastructure support provided by the NIAID, and is conducted in U.S and select international sites (approximately 120 sites in 11 countries). - REPRIEVE (EU5332) is co-sponsored by NEAT ID and MGH, and is conducted at 13 sites in Spain.
The purpose of the Patient and Provider Assessment of Lipid Management Registry (PALM) is to gain a better understanding of physicians' cholesterol medication prescribing practices, patient and physician attitudes and beliefs related to cholesterol management, and current utilization of cholesterol-lowering therapies given the new ACC/AHA guideline recommendations. The PALM Registry hopes to allow for the design of ways to improve cholesterol management and decrease the burden of cardiovascular disease (CVD) in the US.
Participants will be recruited during their hospitalization for either heart attack or unstable angina and will be randomly assigned to either a text message program (Txt2Prevent) or usual care. They will be texted for the first 60-days after discharge. Texts will include topics regarding self-management and discharge protocols such as reminders to make an appointment with their general practitioner or to refill medication prescriptions. After 60 days, the two groups will be compared for hospital readmission rates, quality of life, medication adherence, and self-management.
High blood pressure (BP) is a serious public health problem responsible for heart attack, stroke and kidney failure. One in four adults in Singapore has hypertension. We propose a pilot study in 2 polyclinics in Singapore, 1 deliver a structured multi-component intervention and another usual care. A total of 100 adults with uncontrolled high blood pressure will be followed for 3 months. The intervention includes 1) algorithm-driven antihypertensive treatment for all patients using fixed-dose combination and lipid lowering for high risk patients, 2) motivational conversation for high risk patients; and 3) telephone based follow-ups of all patients by a team of physician supervised nurse practitioners and nurses. The change in BP will be compared between intervention and control groups. The structured care including the above mentioned components is likely to be more effective than usual care in lowering BP levels of patients with uncontrolled high blood pressure. Such a program is also likely to be more cost effective in terms of money spent for improving quality of patients' life. The findings of the pilot will inform the design of a larger cluster randomized trial in eight polyclinics in Singapore. If the main study is successful, the findings will be informative for policymakers to roll out intervention in all polyclinics and primary care centers across Singapore, and other countries with similar healthcare infrastructure.
Background: Patients with obstructive sleep apnea run an increased risk of cardiovascular disease including hypertension. Continuous positive airway pressure (CPAP) is the first line of treatment. However, many patients skip CPAP for some nights. Aims: The primary aim was to investigate the cardiovascular effects of short-term CPAP withdrawal for five nights because of obstructive sleep apnea. Design: Randomized, parallel controlled trial Inclusion criteria: 100 patients with successful CPAP treatment for moderate to severe obstructive sleep apnea. Exclusion criteria: Dementia, heart infarction within 3 months, apnea hypopnea index > 10 with CPAP treatment. Randomization: 50 patients are randomized to sleep 5 days without CPAP and 50 patients to continue with CPAP treatment during the trial. Primary outcomes: Arterial stiffness, 24-hour blood pressure. Secondary outcomes: Effects of gender on outcome. Effects on brain natriuretic peptide, apnea-hypopnea index, oxygen desaturation-index, urine-catecholamines, blood lipids, C-reactive protein, glucose metabolism (S-glc, HBA1c), insulin resistance, serum creatinine, hemoglobin, daytime sleepiness (ESS, KSS), lung function (FVC, FEV1), airway inflammation (exhaled NO) Procedures: Sleep apnea investigation while patients are treated with CPAP for one night. Urinary samplings during the same night. They are also investigated with 24 h blood pressure measurements. Blood samples are taking fasting in the morning followed by measuring the arterial stiffness (Vicorder, Skidmore Medical UK) including pulse wave analysis using sphygmomanometer (Omron Japan). The same investigations are done at follow-up 5 days later where half of the patients have continued using CPAP treatment and half of them has slept without CPAP.
This project will pilot test an intervention to increase participation rates in cardiac rehabilitation and medication adherence among patients following a cardiovascular event. The intervention will use an educational video shown during referral to cardiac rehabilitation (before hospital discharge), along with a brief, telephone-delivered counseling session to increase motivation to participate in cardiac rehabilitation and take all cardiac medications as prescribed (following hospital discharge). One hundred twenty patients who have experienced a cardiovascular event, and who are eligible for cardiac rehabilitation, will be recruited to participate in the study. Three groups of participants (40 each) will be formed: a control group that receives standard care, a first experimental group that sees the educational video and receives motivational counseling to attend cardiac rehabilitation, and a second experimental group that receives motivational counseling to adhere to their medications as prescribed. It is expected that the experimental group participants will differ from the control group participants in rates of participation in cardiac rehabilitation (experimental group #1) and medication adherence (experimental group #2). If successful, this intervention could be used in hospital settings to increase patients' adherence behaviors.
