Ultrasound Guidance for Heart Block

London, Ontario
Each year, over one million pacemakers are implanted globally using x-rays. Recent developments have been aimed at determining which area of the heart is the best option for lead placement. An area in the septum separating the verticals called the left bundle branch area (LBBA) has previously been identified as a safe and effective area for lead placement. However, as the LBBA location is in the center of the heart, it is impossible to see the entire extent using X-ray. Current practice requires x-ray guidance to estimate the location and pacing parameters to confirm proximity. Implanting in LBBA takes longer procedure times and higher exposure to X-ray radiation for both patients and hospital staff. Over time, radiation poses an increased risk of cancer and other medical issues. This study will determine if using ultrasound can improve pacemaker lead implantation to the LBBA. Benefits to patients may include fewer attempts and more accuracy in lead deployment, thereby reducing risks and providing improved outcomes. Benefits to healthcare delivery may include reduction in total procedure time, thereby allowing more cases per day to reduce waitlist, and reduced X-ray exposure to staff thereby reducing cumulative effects.

Anakinra for Heart Failure

Richmond, Virginia
End-stage heart failure (HF) is a progressive illness with a mortality rate similar to most advanced cancers.Roughly 5% of patients with HF have end-stage disease that is refractory to medical therapy (stage D heart failure). When patients reach this point in their disease, the only treatments known to prolong life are cardiac transplantation or left ventricular assist devices. In patients who do not qualify for these options, or elect a palliative approach, inotropes are frequently used to improve hemodynamics through an increase in cardiac output and reduction in filling pressures. While inotropes provide profound symptomatic relief, these benefits are accompanied by significant risks of progressive adverse cardiac remodeling, arrhythmias, and sudden death. There is, therefore, an urgent need to develop strategies to reduce the dose or duration of inotrope use in the management of patients with stage D of HF.

Calcium Channel Blocker + Beta Blocker for Heart Failure

Philadelphia, Pennsylvania
Heart failure with preserved ejection fraction (HFpEF) is a critical public health problem. Heart failure (HF) affects over 5 million adults in the United States (US), and is a major source of morbidity, mortality, and impaired quality of life. Approximately half of individuals with HF have a preserved left ventricular (LV) ejection fraction (EF), termed HF with preserved EF (HFpEF). While there are several effective pharmacologic therapies for HF with reduced ejection fraction (HFrEF), none have been identified for HFpEF. Hypertension, which is present in approximately 80% of individuals with HFpEF, is the foremost modifiable risk factor for the development and progression of HFpEF. Despite the clinical importance of hypertension in HFpEF, there is limited information on how common antihypertensive agents, particularly calcium channel blockers (CCBs) and β-blockers, effect pathophysiologic mechanisms of HFpEF. This is a mechanistic investigation of the role of dihydropyridine CCBs compared to β-blockers (commonly used antihypertensive agents in clinical practice) in targeting key physiologic abnormalities in HFpEF.

Left Bundle Branch vs Right Ventricular Pacing for Heart Block

Montreal, Quebec
High burden right ventricular (RV) pacing has been shown to increase cardiovascular mortality, incidence of heart failure (HF), worsen left ventricular (LV) function and accelerate the development of atrial fibrillation (AF). High percentage ventricular pacing and wider paced QRS in the setting of normal baseline LV ejection fractions have consistently been shown to be independent risk factors for pacing-induced cardiomyopathy. Left bundle branch pacing (LBBP) has emerged as a potential alternative pacing mechanism that may avoid LV dyssynchrony and pacing-induced LV dysfunction by mimicking native electrical conduction.

"I was diagnosed with stage 4 pancreatic cancer three months ago, metastatic to my liver, and I have been receiving and responding well to chemotherapy. My blood work revealed that my tumor markers have gone from 2600 in the beginning to 173 as of now, even with the delay in treatment, they are not going up. CT Scans reveal they have been shrinking as well. However, chemo is seriously deteriorating my body. I have 4 more treatments to go in this 12 treatment cycle. I am just interested in learning about my other options, if any are available to me."

Discontinuing Beta-Blockers for Ischemic Heart Disease

Edmonton, Alberta
Patients with heart disease are often prescribed many medications and these patients may experience drug interactions or negative drug related side effects. With newer medications and treatments available, it is not well known whether older drugs, such as beta-blockers, are still an effective and safe option for treating heart disease. Some evidence suggests beta-blockers should be continued, whereas other evidence suggests beta-blockers might cause unnecessary harm. The study hopes to determine whether continuation or discontinuation of beta-blockers will affect long term cardiovascular outcomes. The study investigators will also examine how beta-blockers continuation or discontinuation affects several quality of life measures.

Paravertebral Block for Post Cardiac Surgery Pain

Vancouver, British Columbia
This study aims to evaluate the efficacy of bilateral, paravertebral blockade (intervention) against sham blocks (control) placed prior to sternotomy in improving quality of recovery following cardiac surgery. Primary outcome: The hypothesis is that bilateral single-shot PVB at the thoracic spinal segmental levels T3/4, compared with sham blocks, improve the Quality of Recovery-15 (QoR-15) score at 24 hours following cardiac surgery by a minimally clinically important difference of 8.0 or greater. Secondary outcomes: The hypothesis is that the intervention will reduce pain scores, opioid requirements, and related side effects; improve respiratory mechanics; and facilitate a better first night's rest/sleep in the first 24-48 hours compared to sham blocks.

Frequently Asked Questions

How much do Heart Block clinical trials pay?

Each trial will compensate patients a different amount, but $50-100 for each visit is a fairly common range for Phase 2–4 trials (Phase 1 trials often pay substantially more). Further, most trials will cover the costs of a travel to-and-from the clinic.

How do Heart Block clinical trials work?

After a researcher reviews your profile, they may choose to invite you in to a screening appointment, where they'll determine if you meet 100% of the eligibility requirements. If you do, you'll be sorted into one of the treatment groups, and receive your study drug. For some trials, there is a chance you'll receive a placebo. Across Heart Block trials 30% of clinical trials have a placebo. Typically, you'll be required to check-in with the clinic every month or so. The average trial length for Heart Block is 12 months.

How do I participate in a study as a "healthy volunteer"?

Not all studies recruit healthy volunteers: usually, Phase 1 studies do. Participating as a healthy volunteer means you will go to a research facility several times over a few days or weeks to receive a dose of either the test treatment or a "placebo," which is a harmless substance that helps researchers compare results. You will have routine tests during these visits, and you'll be compensated for your time and travel, with the number of appointments and details varying by study.

What does the "phase" of a clinical trial mean?

The phase of a trial reveals what stage the drug is in to get approval for a specific condition. Phase 1 trials are the trials to collect safety data in humans. Phase 2 trials are those where the drug has some data showing safety in humans, but where further human data is needed on drug effectiveness. Phase 3 trials are in the final step before approval. The drug already has data showing both safety and effectiveness. As a general rule, Phase 3 trials are more promising than Phase 2, and Phase 2 trials are more promising than phase 1.

Do I need to be insured to participate in a Heart Block medical study?

Clinical trials are almost always free to participants, and so do not require insurance. The only exception here are trials focused on cancer, because only a small part of the typical treatment plan is actually experimental. For these cancer trials, participants typically need insurance to cover all the non-experimental components.

What are the newest Heart Block clinical trials?

Most recently, we added Ultrasound Guidance for Heart Block, Leadless Pacemakers vs. Left Bundle Area Pacing for Heart Block and Anakinra for Heart Failure to the Power online platform.
