Pulmonary HypertensionValvular Heart Disease4 more

The primary purpose of this study is to evaluate the diagnostic performance of three methods for measuring right ventricular size and function including the Philips Novel RV quantification technologies (RV Heart Model volumetric analysis and Philips 2D strain) and the Upper Valley Right Ventricle Algorithm (UVRV) algorithm as compared to the gold standard of volumetric analysis via cardiac magnetic resonance imaging (CMR) in a broad patient population.

Diastolic Exercise Stress Testing in Heart Failure

Heart Failure With Preserved Ejection Fraction

Patients with an intermediate risk (HFA-PEFF score 2-4 points) for heart failure with preserved ejection fraction (HFpEF) will be further investigated with invasive right heart catheterization. All patients with a resting pulmonary artery wedge pressure (PAWP) <15mmHg will undergo the following stress test modalities in a randomized order: (1) bicycle ergometry, (2) dynamic handgrip exercise, (3) 500ml fluid challenge over 5 minutes, (4) leg raise testing. Exercise induced HFpEF will be diagnosed if PAWP rises to >25mmHg.

My Research Legacy Pilot Study

Myocardial InfarctionStroke5 more

The My Research Legacy Pilot Study will establish a participant registry that collects self-reported health data and answers to online survey questions about individual daily choices, diets, and exercise; data from wearable devices; and, (optional) data from genome sequencing analysis. Individuals under the age of 50 who meet eligibility criteria will answer questions using the American Heart Association's (AHA) Life's Simple 7™ My Life Check v4.0 three times over the course of 6 months and transmit data from a Fitbit Charge 2 device. All other individuals who are interested in the study and meet entry criteria may also enroll.

Correlating Noninvasive Cardiovascular Measures to Left Ventricular End Diastolic Pressure in Heart...

Heart Failure

HF001 is a prospective observational study utilizing non-invasive medical devices that may be able to discriminate changes in heart failure while acutely decompensated patients undergo routine interventional therapies in a hospital setting. Subjects will be monitored using CVInsight™ [CVI] via a finger and/or forehead sensor, while performing an isometric handgrip stress test (IHGST). Changes in the CVI signal will be analyzed and correlated to standard assessments of heart failure including pulmonary artery catheter (PAC) pressures, blood pressure (BP), patient symptoms, and physical exam findings. The results of this study will be used to develop a powered study to determine if a new configuration of non-invasive monitoring devices can be used to monitor heart failure status more sensitively than current non-invasive techniques.

Pulmonary Blood Flow Measurements in CHF Patients

Congestive Heart Failure (CHF)

Historically, transthoracic Doppler echocardiography has been unable to provide interpretable data of blood flow within the lung parenchyma because of air attenuation of Doppler signals. Recently, a transthoracic Doppler system known as the Sonara/tek Transcranial Doppler (TCD) System has been developed that can identify parenchymal pulmonary blood flow (PPBF) signals. The ability to non-invasively collect information regarding the pulmonary aspect of the cardio-pulmonary system may provide valuable information and new insights into the structural and functional characteristics of the lung parenchyma and vasculature in health and disease states.

Myocardial Performance at Rest and During Exercise in Heart Failure With Preserved Ejection Fraction...

Heart Failure

This study is being done to study how well the heart contracts and relaxes during exercise. In addition to traditional measures of heart function, we will use a new computer program that may improve understanding of why people feel shortness of breath or fatigue.

Congestive Heart FailureCardiomyopathy

The purpose of this study is to determine if the forehand location for sensor placement has less episodes of signal dropout than the finger sensor location. In addition, this study will evaluate two finger sensors, which utilize different technology to compare signal quality.
