To analyze the fate of side-branch after provisional main vessel stenting based on morphology defined prior to PCI by OCT. Offline analysis of side branch impingement of the ostium of SB leading to acute loss in SB diameter area, carina shift and plaque shift will be also be performed.
NCT01434641
This protocol details a novel myocardial perfusion Single Photon Emission Computed Tomography (SPECT) protocol wherein patients receive a low-dose (6 mCi) of Tc-99m sestamibi during exercise or regadenoson pharmacologic stress and undergo a full-time SPECT acquisition processed with Wide Beam Reconstruction (WBR). Immediately thereafter patients receive a high-dose (30-35 mCi) of Tc-99m sestamibi at rest and undergo a half-time rest scan, also processed with WBR. All enrolled research subjects will undergo both the initial stress and subsequent rest scan. The radiation exposure associated with this new stress/rest protocol is equivalent to that of the conventional rest/stress protocol presently in routine clinical uses at SLRHC. Eventually, when and if this novel stress/rest protocol is adopted in routine clinical practice, patients with normal stress scans would receive only 6 mCi of Tc-99m sestamibi (331 mSv in men, 241 mSv in women) and spend only approximately one hour in the Nuclear Medicine Laboratory. All patients presenting to the Nuclear Medicine Laboratory for evaluation of known or suspected coronary artery disease will be candidates for enrollment. Fifty patients undergoing treadmill exercise stress and 50 patients undergoing regadenoson pharmacologic stress will be enrolled. Pregnant and breast-feeding patients will not be eligible.
NCT00120289
The purpose of this study is to determine whether raising "good cholesterol" with a drug based on the vitamin niacin, while lowering "bad cholesterol" with a statin drug, can prevent more heart disease than the statin alone.
NCT01343667
The objective of this study is to provide an ongoing evaluation of clinical outcomes associated with the GORE Flow Reversal System and the GORE Embolic Filter when used for embolic protection during carotid artery stenting.
NCT00005240
To test the hypotheses that hypertensive emergency was associated with non-compliance with antihypertensive medication, low level of contact with the medical care system, and alcohol abuse and cigarette smoking. Also, to describe the clinical characteristics of patients hospitalized with hypertensive emergency including morbidity, mortality, and cost, and the extent to which hypertensive emergency occured among previously diagnosed and treated hypertensives.
NCT00006501
To evaluate whether T Wave Alternans can predict ventricular arrhythmias and sudden cardiac death (SCD) in a prospective epidemiologic natural history study. The prospective epidemiologic pilot study included 550 patients that had left ventricular dysfunction and no history of sustained ventricular arrhythmias. The primary hypothesis tested was whether there was an increased risk of having an arrhythmic event when T Wave Alternans was present in the patient. The secondary aims included comparing risk due to T Wave Alternans between the ischemic patients and non-ischemic patients and assessing whether T Wave Alternans remained an independent predictor of risk upon adjustment for other known risk factors for arrhythmic events such as ejection fraction, ventricular ectopy, NSVT, average NN interval, and RR interval variability. The study approach was a standard epidemiologic surveillance technique. The subject population consisted of individuals with Class I to III heart failure who will underwent a TWA and Holter monitor test and then were followed for up to two years or until arrhythmic events occured.
NCT00000607
To conduct a randomized, unblinded clinical trial comparing the left ventricular assist device (LVAD) with maximum medical management in patients with end-stage heart failure who were not candidates for heart transplantation.
NCT01144182
Heart failure (HF) greatly increases mortality and lowers quality of life (QOL). HF is the most common indication for readmission in older adults and the most frequent reason for 30-day readmission. Medications and restriction of dietary sodium constitute crucial therapy to lower HF recurrence. However, adherence to medications and dietary recommendations is low in HF patients. Nonadherence is often due to an interaction among the environment, the patient and providers. In the VALOR in Heart Failure Study, we will assess a novel quality improvement program (QIP) to improve HF care using a pretest-posttest design. This interdisciplinary theory-based prospective experimental study will target improving HF treatment using patient-based behavioral and checklist intervention, as well as provider and system-targeted checklists and treatment defaults (posttest or intervention phase); this will be compared to current best practice (CBP) evaluated in the pretest (pretest or pre-intervention) phase. It is hypothesized that the QIP, which intervenes on patient, provider and system levels, will improve QOL and lower HF recurrence compared to CBP.
NCT01707524
The aim of this study is to measure radiation exposure during coronary angiography (CA) with a trans-radial approach (TRA), specifically comparing access via the left versus right radial artery in patients with suggested clinical predictors of TRA failure/difficult. These predictors include age \>70, female gender, height \<64 inches, and history of hypertension.The study also aims to determine difficulties encountered during left or right radial access in this specific patient population. A secondary aim is to compare the results of enrolled patients with a registry of patients where femoral access was obtained. Currently more than 1 million percutaneous coronary interventions (PCI) are performed in the United States annually. There is a growing trend to perform procedures utilizing the TRA due to recent data demonstrating decreased bleeding and access-site complications compared to the femoral approach. However, the TRA approach is also know to be associated with greater radiation exposure compared to the femoral approach. Furthermore, the TRA to catheterization may be difficult in certain populations because of anatomic considerations. Though traditionally completed via canalization of the right radial artery (RRA) due to feasibility with room setup, left radial artery (LRA) access may be superior due to the shorter distance needed to reach the ascending aorta and bypassing the tortuosity of the right subclavian artery. Given the benefits of the TRA, it is important to determine how left versus right radial artery access affects parameters of radiation exposure in addition to procedural difficulty. This study will be a prospective, randomized study of patients with suggested predictors of TRA failure/difficulty referred for coronary angiography. Patients referred for coronary angiography using the trans-radial approach will be randomly assigned to obtain arterial access via the right or left radial artery. A registry of patients referred for coronary angiography using the trans-femoral approach will be compiled. The primary outcome measure will be radiation exposure as measured by dose area product output from the coronary angiography system. Secondary measures will include the total fluoroscopy time, total dose of radiation, number of catheters used, and incidence of subclavian tortuosity. In addition, procedural complications and success rates will also be evaluated.

NCT00263042
The primary objective is to show whether rimonabant reduces the risk of a heart attack (MI), stroke, or death from an MI or stroke in patients with abdominal obesity with other cardiovascular (CV) risk factors. The secondary objective is to show whether rimonabant reduces the risk of MI, stroke, CV death, or CV hospitalization in these patients.
NCT01954160
Congestive heart failure is a common disorder in which the heart cannot pump enough blood to meet the needs of the rest of the body. Poor sodium handling by the kidneys is a damaging effect of heart failure, and it leads to symptoms of congestion such as shortness of breath or ankle swelling. Recent studies suggest that reducing the nerve activity to a kidney could reduce sodium retention and blood pressure. An improvement in the way the kidneys handle sodium may reduce disease progression and decrease symptoms for heart failure patients.
NCT01067859
NCT00887588
The study will assess the effects of 36 weeks of treatment with LCZ696 compared to valsartan on N-terminal pro-Brain Natriuretic Peptide (NT-proBNP) in patients with chronic heart failure and preserved left-ventricular ejection fraction.
NCT01832493
The Sensor Optimization of Cardiac Resynchronization Therapy (CRT) Response (SOCR) Study is a multicenter, prospective, non-randomized acute feasibility study that is being conducted to determine if subcutaneous heart sounds and/or intracardiac impedance can acutely identify the optimal atrioventricular (AV) pacing intervals and optimal left ventricular (LV) electrodes in patients indicated for cardiac resynchronization therapy.
