Clinical trials: Myocardial Strain
Aging, Heat Stress
Impact of Extreme Heat on Myocardial Blood Flow and Flow Reserve in Young and Older Adults
Extreme heat causes a disproportionate number of hospitalizations and deaths in older adults relative to any other age group. Importantly, many hospitalizations and deaths are primarily due to cardiovascular events such as…

Ischemic Cardiomyopathy
Comparison of Two Exercise Training Modes on Left Myocardial Regional Function After Myocardial Infarction Evaluated by 2D Strain Ultrasound
Ischemic cardiomyopathy, defined by a deficiency in oxygenation of the myocardium due to a narrowing of the coronary arteries, is a major problem for public health.

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