Filter by:Some patients with a long history of AF develops PH "reactive" type with an increase in pulmonary vascular resistance due to vasoconstriction or structural changes of the vascular wall. RFA PVI + RFA GP is the "gold standard" in the treatment of patients with persistent AF, do not respond to optimal therapy. The rear area of the pulmonary artery bifurcation is adjacent to the roof and part of the front of the left atrium. In the projection of this area are ganglionic plexus of the left atrium, the sympathetic nerve fibers of the pulmonary artery and baroreceptors main pulmonary artery.Recent studies have shown that radiofrequency denervation of the pulmonary artery improves the quality of life in patients with PH.
Background The burden of sudden cardiac death (SCD) in Africa is unknown. Our aim is to assess the epidemiology of SCD in Africa. Methods The sub-Saharan Africa SCD study is a prospective, multicenter, community-based registry monitoring all cases of cardiac arrest occurring in victims > 15 years old. Investigators will use the definition of established SCD if an unexpected death without obvious extracardiac cause, occurred with a rapid witnessed collapse, or if unwitnessed, occurred within 1 hour after the onset of symptoms; probable SCD if an unexpected death without obvious extracardiac cause occurred within the previous 24 hours. After approval from institutional boards, Investigators will record demographic, clinical, electrocardiographic and biological variables of SCD victims (including survivors of cardiac arrest) in several sub-Saharan African cities. All deaths occurring in residents of districts of interest will be checked for past medical history, circumstances of death, and autopsy report (if possible). Investigators will also analyze the employment of resuscitation attempts during the timeframe of sudden cardiac arrest (SCA) in various patient populations throughout countries. Conclusion This study will provide comprehensive, contemporary data on the epidemiology of SCD in sub-Saharan Africa and will help in the development of strategies to prevent and manage cardiac arrest in this region of the world.
1. Research background - High blood pressure is one of the most important risk factors to cardiovascular diseases (CVDs). Reducing population blood pressure can control CVD incidence and lower mortality effectively. Much research has proven that adjusting for Na and K intake level can reduce blood pressure. According to the China Salt Substitute Study, the systolic blood pressure of intervention group which used salt substitute is 5.4 mmHg lower than that of control group. Life expectancy in Tibet is 67 years old. It is estimated that the use of salt substitute among population in Tibet can reduce total mortality in Tibet by 20%. China Salt Substitute Study in Tibet (CSSS-Tibet), found that salt substitute is effective in lowering both systolic and diastolic blood pressure and offers a simple, low-cost approach for hypertension control among Tibetans in China (unpublished results). However, the study focused on hypertensive patients, the effectiveness of hypertension control by providing free salt substitute to the entire population remains unknown, and a large-scale trial is needed. 2. Objectives - Primary objective is to observe the effect of providing salt substitute on population blood pressure in Tibet. Secondary objective is to observe the effect of such intervention on population mortality, cardiovascular mortality and life expectancy. In addition, the data collected from high-risk population (sub-group) in the study will be used in China Salt Substitute and Stroke Study (SSaSS). Also, serum cholesterol and random blood glucose of people over 60 in Tibet will be collected. 3. Method - The study is a open, cluster-randomized, controlled trial. - 30 villages with 15 to 35 households each and a distance of at least five kilometers in between will be selected from Damxung county and Maizhokunggar county. The two counties have an average altitude of over 4000 meters in Tibet Autonomous Region. - All selected villages will be randomly assigned to intervention group or control group on a 1:1 ratio. - All household in the selected villages will be recruited if they meet the eligibility criteria. Approximately 4,500 participants will be enrolled - Intervention group receives free salt substitute. Control group will continue to buy their own normal salt. Both group will receive the same health education on salt reduction. 4. Outcome - Primary outcome is blood pressure. Secondary outcomes include total mortality, cardiovascular disease mortality, life expectancy, serum cholesterol level of people over 60, and random blood glucose level of people over 60.
This study wants to investigate the hemodynamic changes in cardiopatic patients undergoing major non cardiac surgery, during and after the continuous infusion of levosimendan or dobutamine.
Ticagrelor therapy has been shown to reduce the rates of cardiovascular events and all-cause mortality compared to clopidogrel therapy in patients with acute coronary syndromes (ACS). The benefit of this study would be to demonstrate that ticagrelor therapy is associated with equivalent platelet inhibition irrespective of the disease status in patients undergoing PCI.
The aim of this study is to determine whether a new vectorcardiogram (VCG) analysis will facilitate the detection of significant coronary disease (CAD) in patients with normal rest 12-leads ECG (NE).
The cyclic movement of the heart and the coronary arteries induces relative axial movement between the artery and a pre-deployed intra-luminal stent which may cause malpositioning. Using a new imaging algorithm to indicate the position of a stent in patients undergoing percutaneous coronary intervention (PCI), the investigators will measure the pre-deployment relative, intra-luminal stent axial movement in the different coronary arteries to facilitate the precise deployment site.
The purpose of this study is to determine whether treating pre-diabetic & pre-hypertensive individuals using multiple drugs intervention (anti-hypertensive drugs (i.e., ACEI) plus anti-glycemic drug (i.e., metformin) plus anti-hyperlipidemic drug (statin)) would lower Cardiovascular Disease (CVD) events.
Background: Type 2 Diabetes Mellitus (T2DM) is associated with an increased burden for cardiovascular disease (CVD). Multifactorial interventions are necessary to reduce the CV risk in T2DM. Bariatric surgery appears to be an alternative for the multifactorial intervention in T2DM associated with obesity. Data have shown, that clinical trial aiming at the control of CVRF in T2DM may not translate in the reduction of CV events. Hypothesis: Intensive medical treatment (IMM) including Roux-en-Y Gastric Bypass (RYGBP) could be superior in the control of the progression of subclinical atherosclerotic disease, as evaluated by carotid ultrasound, in subjects with T2DM and a BMI between 30.0 and 34.9 kg/m2.The primary aim of the study is To compare the effects of intensive medical treatment (IMM) including Roux-en-Y Gastric Bypass (RYGBP) and IMM alone on the progression of the carotid intima media thickness (CIMT) at 24 months after entry into the trial relative to baseline.Methodology: Two-year Randomized Clinical Trial, including 240 patients
The aim of this study is to assess in the sample of population resident in the KHUMBU valley (NEPAL): 1. the respiratory function decline by means of spirometry and the respiratory health by means of questionnaire and six-minute walking distance 2. the presence of markers of early atherosclerosis with ultrasound and to estimate the value of systolic pulmonary pressure in comparison with not exposed subjects. The investigators hypothesize that the chronic exposure to indoor pollution 1. can accelerate the physiological respiratory function decline, usually around 15-20mL/year in healthy subjects 2. induce cardiovascular impairment The population of high altitude villages is a unique sample to study the effect of the only indoor pollution. In fact, the absence of traffic, due to the lack of roads, and the very low level of smoking habits allow to have no other confounding factors 3. to study and analyze how the architectural features of the buildings of the village (distribution of domestic locals, natural or non natural ventilation systems, domestic activities, materials used, etc.) affect the indoor pollution from carbon monoxide, which necessarily is developed indoor during the daily life activities. What the project prospects is to gather information focused on the scale of the building, independently from the typology, to study a model that will help to describe which aspects are most important to what concern the genesis of the pollution of the indoor air.
