Filter by:This is a phase 1, single-blind, randomized, placebo-controlled, multiple ascending dose study aimed to assess the safety, tolerability, and pharmacokinetics of GS-6615 in healthy subjects.
Persons voluntarily attending the Community Center of the Atahualpa Project during one calendar year will be evaluated by trained personnel to check their cardiovascular health status. A chart with information of healthy behaviors as well as the numbers of the person's blood pressure, fasting glucose, and total cholesterol levels will be given. Persons who sign the informed consent will be visited at their homes after 3 months and than every year up to five years. The idea is to check whether the person followed our advises and if that compliance iis associated with improvement in the cardiovascular status or with a decreased incidence of stroke and ischemic heart disease, when compared with persons who did not attend the community center or those who did not follow our advices.
The purpose of this study is to determine Isoflurane's dose-dependent effect on left ventricular (LV) systolic function in cardiac surgery. The change of tissue Doppler imaging (TDI) of lateral mitral valve annular systolic velocity at three different isoflurane concentrations would be analyzed by using intraoperative transesophageal echocardiography (TEE) in cardiac surgery patients.
The objective for this pilot study is to develop an optimized, clinically usable myocardial PET-MR perfusion protocol and to determine which of all data potentially available should be acquired for a clinical myocardial perfusion examination. Hypothesis: The hypothesis is that high resolution, high sensitivity DCE MRI could replace the rest PET myocardial perfusion imaging, significantly decreasing examination time and patient radiation dose while maintaining the comprehensive reference-quality PET myocardial stress perfusion coverage. The primary outcome will be comparison of diagnostic accuracy of each combination of imaging to detect clinically significant coronary artery stenosis (≥70% diameter stenosis).
The purpose of the study is 1> to compare neointimal stent coverage after OCT-guided vs. Angio-guided PCI, 2> to compare neointimal stent coverage at 3 months after EES vs BES implantation, 3> to determine the duration of dual antiplatelet therapy by OCT measurement at 3 months
The purpose of the study is to make a head-to-head comparison of weight loss and interval training as methods of secondary prevention in overweight patients with ischemic heart disease.
The purpose is to investigate how the adsorptive capacity of the active carbon filter to carbon dioxide in an anaesthetic gas reflector (AnaConDa) is affected by adding inhaled anaesthetic agent. The hypothesis is that addition of inhaled anaesthetic agent will affect the amount of adsorption of carbon dioxide to the active carbon and thereby affect rebreathing of carbon dioxide.
The investigators intend to prospectively enroll consecutive patients, without known ischemic heart disease, referred by their physician for routine exercise MPI at a tertiary care center. Prior to the MPI (nuclear stress test), eligible and consenting patients will undergo a one-hour period of Holter ECG digital recording. Application of ECG electrodes will be performed by medical technicians following standard recommendations, utilizing approved Holter device & stickers. The Holter ECG data will be used for the offline heart rate variability (HRV) analysis by the HeartTrends device. Immediately following data acquisition, all patients will undergo an exercise MPI according to accepted clinical practice guidelines. Following the MPI, there will be no interference with patient management, which will be conducted by the patients' treating physicians according to current guidelines, unaware of HRV results. Analysis of recorded ECG data for HRV will be performed blinded to the EST and MPI results, by HeartTrends device. The results of the HRV tests will not be available to treating physicians and will not be used to guide patient management. Patients will be followed for 6 months for the occurrence of coronary interventions and MACE, defined as: death, myocardial infarction, unstable angina, or any coronary revascularization.
The aim of the Atahualpa project is to evaluate the cardiovascular (CVH) status of the inhabitants of a rural village of coastal Ecuador as well as to determine the prevalence and retrospective incidence of stroke and ischemic heart disease. The protocol may be used as a pilot for large-scale studies attempting to evaluate the CVH of rural or even urban centers of Latin America, to implement cost-effective strategies directed to reduce the burden of stroke and cardiovascular diseases in the population at large.
During cardiac displacement for off-pump coronary artery bypass(OPCAB) surgery, the presence of air underneath the displaced heart compromises the transgastric (TG) window for transoesophageal echocardiography(TOE). The investigators hypothesised that placing a saline-filled glove would enhance TG transmission of ultrasound and facilitate TOE imaging for monitoring left-ventricular regional wall motion (LV-RWM). For left circumflex coronary artery (LCX) grafting in OPCAB surgery (n=13), mid-oesophageal (ME) and TG TOE images are recorded before cardiac displacement (T control), after displacing and stabilising the heart (T-displaced), and after placing a saline bag (saline-filled surgical glove) underneath the displaced heart (T-saline bag). Following data are determined by integrated TG and ME TOE views (ME+TG) at T-control, T-displaced and T-saline bag: number of readable segments (NRS) in a 17-segment model; NRSs in basal and mid-TG short axis views; NRS in 5-LV segments of the LCX territory; the incidence of inadequate monitoring of LV-RWM (NRS < 14/16 except for the apex in 17-segment model).
