Filter by:This is a randomized, prospective, single-blinded trial to determine the overall rate of successful His-Purkinje conduction system pacing Optimized Trial of Cardiac Resynchronization Therapy (HOT-CRT) versus biventricular pacing using coronary sinus lead (BVP) to compare acute and mid-term outcomes. Acute outcomes include change in QRS duration pre-and post-pacing (degree of QRS narrowing) and incidence of major periprocedural complications (pericardial tamponade, need for lead revision, etc.). Mid-term outcomes include echocardiographic response at 6 months along with a composite clinical outcome of heart failure hospitalization, ventricular arrhythmias, crossover, and all-cause mortality.
Between 25% and 30% of patients hospitalized for acute heart failure (AHF) are readmitted within 90 days after discharge. Mostly due to persistent congestion on discharge. However, as the optimal evaluation of decongestion is not clearly defined, it is necessary to implement new tools to identify subclinical congestion to guide treatment.
It is well known fact, that prediabetes is a predictor of high cardiovascular mortality, increasing the risk of developing such adverse cardiovascular events as myocardial infarction, stroke and sudden cardiac death. The key pathogenetic link in development of carbohydrates metabolism disorders (CMD) is insulin resistance (IR), which is one of the crucial mechanisms for the development and progression of chronic heart failure (CHF). IR disrupts the functioning of the myocardium due to endothelial dysfunction, inflammation, oxidative stress, remodeling and impaired myocardial metabolism. In condition of a combination of CMD and CHF the reverse development of hyperglycemia is also difficult due to hyperactivation of neurohormonal systems - renin-angiotensin-aldosterone system, in particular. So, drug therapy should neutralize the undesirable metabolic effects of hyperglycemia on the course of CHF, as well as prevent the development of micro- and macrovascular complications. The study will investigate the ability of metformin to impact on clinical and laboratory (neurohormonal, lipid profiles, renal function) parameters of ischemic etiology heart failure patients with prediabetes, as well as their quality of life and prognosis (incidence of adverse cardiovascular events). These tests will be assessed at the beginning and repeated after one year. At the end of the study we will investigate the difference between lifestyle modification effect and metformin treatment. The study is funded by Ministry of Education and Science of Kyrgyz Republic.
Background: Diabetes, and especially diabetic kidney disease is associated with the development of cardiovascular disease such as calcification in the coronary arteries and heart failure. Sleep apnea is frequent among patients with diabetes and diabetic kidney disease and sleep apnea itself is a solitary risk factor in the development of cardiovascular disease. Nonetheless, sleep apnea is underdiagnosed in diabetes patients because of a discrepancy between sleep apnea severity and actual oxygen deficiency symptoms which makes the diagnosis difficult. For that reason, many diabetics have undiagnosed sleep apnea together with cardiovascular disease. Early discovery of sleep apnea among high risk diabetic patients may therefore be considered crucial before cardiovascular complications develop. For this reason, sleep apnea screening of high-risk diabetics can possibly improve early diagnostics of cardiovascular disease. Aim: This study will seek to establish the association between obstructive sleep apnea (OSA) and coronary calcification and heart failure in patients with diabetic kidney disease. The basic hypothesis of the study is that patients with diabetic kidney disease and concurrent OSA have a higher prevalence and severity of coronary calcification and heart failure compared to patients without OSA. Methods: Diabetic adult patients with scheduled check-ups at Steno Diabetes Center Aarhus, or Department of Renal Medicine on Aarhus University Hospital will be included in the study. Firstly, all included patients are screened for sleep apnea with the devices SomnoTouch® and ApneaLink®. Based on the sleep apnea determination; 40 patients with moderate-severe sleep apnea are compared with 40 patients without sleep apnea. In both groups, the patients are examined for calcification in the coronary vessels using a CT-scan while the function of the heart is examined by ultrasound (echocardiography). The stiffness of aorta is measured and performed using radial artery tonometry (SphygmoCor®). Furthermore, range of blood- and urine samples will be performed The perspectives are that patients with diabetes should be regularly evaluated for sleep apnea and that patients with moderate/severe sleep apnea should undergo further examination for cardiovascular disease even though the patients don't display any symptoms of either cardiovascular disease or sleep apnea.
This study will develop and test the effectiveness of a culturally-sensitive, telephone-based, tailored dyadic problem-solving intervention to improve self-care in rural heart failure (HF) dyads. The target population is rural-residing HF dyads (patient and family caregiver). Rural dyads will be recruited from the Florida State University Institute for Successful Longevity Participant Registry, outpatient HF/cardiac and rural healthcare clinics affiliated with the Tallahassee Memorial Hospital, Bond Community Health Clinic, via social medial and newspaper ads, and publicly available community sites (e.g., senior centers, post offices, grocery stores, etc.). Phase I (Arm I) will include a one-time telephone-based semi-structured interview. Dyads in Phase II (Arm II) will receive one telehealth (virtual or telephone) session, followed by 7 follow-up telephone sessions.
This is a prospective, post-market, multi-center, non-blinded, single arm study of the HeartMate 3 Left Ventricular Assist System (LVAS). The objective of this study is to evaluate the implantation of the HM3 utilizing techniques other than full median sternotomy (e.g. thoracotomy) and impact on post-implant length of stay.
Our aim is to assess whether changes in CO, CI and SVR as measured using the Biobeat wearable, wireless, non-invasive device during IV diuretic administration in an outpatient setting among CHF patients correlate with short-term clinical change measured using symptoms questionnaires, change in weight and urine output. We will also assess the correlation between baseline values of those parameters and long-term clinical outcomes, measured by HF hospitalizations and the change in disease perception and quality of life reported in questionnaires.
Suboptimal optimization of atrio-ventricular (AV) and inter-ventricular (VV) timings could affect the clinical response of CRTd in T2DM patients. Thus, authors hypothesize that automatic sensor guided CRTd optimization could ameliorate clinical outcomes in patients with T2DM. However, authors will evaluate the effects of cardiac resynchronization therapy (CRTd) in patients with type 2 diabetes mellitus (T2DM) optimized via automatic vs. echocardiographic guided approach.Authors will conduct a prospective, multicenter study to recruit, from October 2016 to June 2019, patients with T2DM and heart failure (HF) candidate to receive a CRTd. After CRTd the patients will be optimized via automatic vs. echocardiographic guided approach.
Part I: Week 0-12: Quantify the effects of lower heart rate (HR) elevation on symptoms and function in patients with heart failure with preserved ejection fraction (HFpEF). The investigators hypothesize that a personalized lower HR elevation employing physiological conduction system pacing in patients with HFpEF will decrease left atrial and left ventricular filling pressures. The investigators expect that this will result in a symptomatic and functional improvements and reduce NTproBNP levels. Additionally, HR elevation may have the potential to reduce the risk for heart failure hospitalization, atrial fibrillation (AF), and cerebrovascular stroke as these outcomes are increased in patients with a normal or preserved ejection fraction on HR lowering treatments. After undergoing pacemaker implantation participants will be randomized to one out of three treatment arms (a) Bachmann's bundle pacing, (b) Bachmann's bundle and His bundle pacing, (c) no pacing with cross-over to alternative treatment arm at week 4 and 8, respectively. The lower pacing rate in arms a and b will be programmed to the personalized lower heart rate for 24 hours a day (the patient's intrinsic heart rate can exceed the personalized lower rate limit). Part II: Week 13-20: Determine the effects of nocturnal heart rate elevation on symptoms and function in patients with HFpEF. The investigators hypothesize that a moderate HR elevation to 110bpm delivered for 10 hours between 8PM to 6AM will provide additional hemodynamic benefits and will lead to beneficial ventricular remodeling. After week 12 the participant will undergo randomization to one of two treatment arms (a) Bachmann's bundle and His bundle pacing, (b) Bachmann's bundle pacing, His bundle pacing and nocturnal pacing. The participant will cross-over to the other treatment arm after 4 weeks (study week 16).
