1. A Study to Assess Non-invasive Arterial Air Plethysmography of Normal and Abnormal Arterial Hemodynamics

   Rochester, Minn.

   The purpose of this study is to determine the accuracy (sensitivity, specificity, negative predictive value, positive predictive value) of a non-invasive arterial air plethysmography prototype in people with normal and abnormal arterial hemodynamics.

2. (FMD Impact Registry) Fibromuscular Dysplasia Findings and Outcomes

   Rochester, Minn.

   To describe the clinical, laboratory, pathologic, imaging findings, therapy and outcomes in all patients with Fibromuscular Dysplasia (FMD) and/or segmental arterial mediolysis evaluated at Mayo Clinic retrospectively (back to 01/01/1990) and prospectively (starting 04/13/2016).

3. A Study to Evaluate the Impact of Menopause on Blood Pressure Regulation During Exercise

   Rochester, Minn.

   The purpose of this study is to determine how menopause influences blood pressure responses during exercise in women.

4. A Study of Heart Muscle Elasticity Measured by Echocardiography

   Rochester, Minn.

   The purpose of this study is to evaluate the possibility of using echocardiography to measure heart muscle elasticity in clinical practice.

5. A Study of Lung Ultrasound to Assess Extravascular Lung Water

   Rochester, Minn.

   The purpose of this study is to determine if lung ultrasound surface wave elastography (LUSWE) can accurately detect changes in lung elasticity (compliance) caused by the presence of extravascular lung water  (pulmonary edema).

6. His Bundle Pacing in Bradycardia and Heart Failure

   Rochester, Minn.

   Participants in this study will either have heart failure (HF) and are scheduled to undergo cardiac resynchronization therapy pacemaker (CRT-P) or cardiac resynchronization therapy defibrillator (CRT-D) implantation, or have atrioventricular (AV) block and are scheduled to undergo dual chamber pacemaker implantation. In this study additional heart rhythm measurements will be collected during the implant procedure to better understand how His bundle and/or parahisian pacing (HISP) effects electrical conduction in the hearts of patients with HF or AV block. The hypothesis is that His bundle or parahisian pacing (HISP) may normalize atrioventricular (AV) conduction with a narrow combination of the Q wave, R wave and S wave (QRS complex) in functional bundle branch block or conduction delay in patients with heart failure (HF).

7. Expanded Access Protocol of Patisiran for Patients With Hereditary ATTR Amyloidosis (hATTR)

   Rochester, Minn.

   The purpose of this study is to provide expanded access of patisiran to patients with hereditary transthyretin-mediated amyloidosis (hATTR).

8. the Mayo Cardiac Sarcoid Registry

   Rochester, Minn., Jacksonville, Fla.

   Aims, purpose, or objectives:

   1. Develop a retrospective registry of patients with cardiac sarcoidosis
   2. Develop a prospective registry of patients with cardiac sarcoidosis
   3. Understand the natural history of cardiac sarcoidosis through evaluation of outcomes of patients in the registry
   4. Determine risk factors for sarcoid involvement of the heart
   5. Evaluate outcomes of patients both treated and untreated with cardiac sarcoidosis
   6. Understand the complications of untreated and treated cardiac sarcoidosis

    

9. A Study to Identify the Genetic Defect(s) in Individuals with Arrhythmogenic Bi-Leaflet Mitral Prolapse (aBiMVP)

   Rochester, Minn.

   The purpose of this study is to elucidate the genetic basis of aBiMVP in hopes of determining novel mechanisms that underlie aBiMVP pathogenesis.

10. A Study to Compare the Effectiveness of Different High-intensity Interval Training Programs in Cardiac Rehabilitation

    Rochester, Minn.

    The main purpose of the study is to examine the effect of two different high intensity interval training (HIIT) prescription approaches on improving fitness, heart function, and the ability of the body's muscles to receive oxygen. The two approaches of the same total exercise durston will include: 1) HIIT with progressively increased interval durations (PRO-HIIT) versus 2) HIIT with constant shorter interval durations (CON-HIIT). The study hypothesis is that the progressively increased interval duration at high-intensity (PRO-HIIT) will result in a greater increases in fitness, heart function, and the ability of the body's muscles to receive oxygen in patients enrolled in cardiac rehabilitation.
