Study summary

At the Malcom Randall Veterans Affairs Medical Center (MRVAMC), invasive cardiac pressures are routinely recorded after transcatheter aortic valve replacement (TAVR) procedures. Our research has disclosed that patients with abnormal hemodynamics (narrow aortic to ventricular end-diastolic pressure difference, indexed to heart rate) suffer from high long-term mortality, compared with patients with normal hemodynamics.This hemodynamic value can be referred to as the aortoventricular index (AVi). Hypertension and diastolic dysfunction are highly co-morbid conditions among these patients. The selective aldosterone receptor antagonist eplerenone (Inspra) is approved for use in the treatment of hypertension. Research also supports that eplerenone may be able to improve diastolic function.

This prospective study is interested in determining 1) the tolerability of eplerenone, and 2) feasibility of administering the Kansas City Cardiomyopathy Questionnaire (KCCQ-12) among subject with abnormal cardiac hemodynamics after TAVR. This study will set the stage for a pilot randomized trial to evaluate eplerenone versus placebo among patients with abnormal hemodynamics after TAVR.

Read the detailed description

Our research has disclosed that patients who have abnormal invasive cardiac hemodynamics (narrow aortic to ventricular end-diastolic pressure difference, indexed to heart rate) after TAVR suffer from poor long-term survival. This hemodynamic value can be referred to as the aortoventricular index (AVi). In a single center observational study, the 2-year mortality rate for patient with a value ≥0.6 mm Hg/bpm was 25% compared with 36% for patients with a value \<0.6 mm Hg/bpm. An abnormal AVi was an independent predictor for poor survival. Hypertension and diastolic dysfunction are 2 highly co-morbid conditions among these patients. Currently, there is lack of appreciation that pressure measurements obtained at the time of TAVR can provide long-term prognostic value. There is also a lack of understanding on how to improve outcomes and quality of life among such patients.

Eplerenone is a selective aldosterone receptor antagonist approved for use for treatment of hypertension. Animal studies have shown that aldosterone receptor antagonists can decrease interstitial myocardial fibrosis. The non-selective aldosterone receptor antagonist, spironolactone 25 mg daily compared with placebo was shown to improve diastolic function, as assessed by echocardiography, among 28 elderly subjects. A meta-analysis of eleven studies in 942 subjects found that aldosterone receptor antagonists improve diastolic function and markers of cardiac fibrosis without significant changes to left ventricular mass or dimensions. In a randomized controlled trial, eplerenone was found to be safely tolerated among asymptomatic patients with moderate to severe aortic stenosis.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

  1. Enroll 10 subjects with hypertension and abnormal hemodynamics after TAVR.
  2. This is a greater than minimal risk study.

Inclusion criteria

  1. Inclusion criteria:

    • TAVR procedure performed at the Malcom Randall VA Medical Center within the last 2 years.
    • Intracardiac pressures recorded 5 to 10 minutes after TAVR and AVi \< 0.6 mm Hg/bpm.
    • History of hypertension, taking anti-hypertensive medications, or recent systolic blood pressure ≥130 mm Hg.

Exclusion criteria

  • Serum potassium >5.5 mEq/L at initiation.

    • Concomitant administration of strong inhibitor (i.e. ketoconazole, itraconazole, nefazodone, troleandomycin, clarithromycin, ritonavir, and nelfinavir).
    • Type 2 diabetes with microalbuminuria.
    • Serum creatinine >2.0 for men and >1.8 for women.
    • \<50 cc/min.
    • Concomitant administration of potassium supplements or potassium-sparing diuretics.
  1. Subjects who are eligible to participate and signed an will be given eplerenone 50 mg daily. Study drug (eplerenone) will be paid by the North Florida Foundation for Research and Education for the duration of the study.

    a. Down-titration or termination of non-essential anti-hypertensive agents is permissible so that eplerenone does not result in hypotension. Essential medications are as follows:

    • Angiotensin converting enzyme inhibitors (ACE-inhibitors) or angiotensin receptor blockers, if intolerant to ACE-inhibitors are indicated for treatment left ventricular dysfunction (i.e. ≤40%), diabetes, and proteinuric chronic kidney disease.
    • Beta-blockers are indicated 3 years after an acute myocardial infarction, unless there is persistent left ventricular dysfunction (i.e. left ventricular ejection fraction ≤40%).
  2. Monitoring.

    a. Serum potassium within the last 30 days is required before initiating eplerenone. Repeat blood draw is required within the first week, and one month after the start of treatment with eplerenone.

  3. Quality of life questionnaire. a. The Kansas City Cardiomyopathy Questionnaire (KCCQ-12) will be administered at baseline and 8 weeks. The KCCQ-12 instrument will be mailed to the subject. Study coordinator will call the subject at 8 weeks to confirm vital status, assess if any adverse reactions from eplerenone, and provide assistance to completing the KCCQ-12, if needed.
Terms in these criteria, in plain language(4)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

CYP3A (CYP3A4) inhibitors and inducers

CYP3A is a group of enzymes, mainly CYP3A4, in the liver and gut that break down many medicines. Some medicines, supplements and foods (grapefruit, St John’s wort) slow them down or speed them up, which changes how much of a study drug stays in the body.

Studies list them so they can be avoided or switched; bring a list of everything you take, including supplements.

Creatinine clearance (CrCl)

How quickly the kidneys clear creatinine, a waste product, from the blood. A study may estimate it from a blood test with age, weight and sex (often by the Cockcroft–Gault formula), or measure it using blood and urine collected over a set time. Given in mL/min; higher is better.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

LVEF (left ventricular ejection fraction)

The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
