  • Hsu Lab

    Principal Investigator:
    Steven Hsu, M.D.
    Medicine

    Our work is focused on the translational human in vivo and ex vivo assessments of right ventricular (RV) function in the setting of pulmonary hypertension.

    Among patients with group I pulmonary arterial hypertension PAH, those with systemic-sclerosis-associated PAH (SSc-PAH) have a particularly poor prognosis and less optimal response to PAH-guided therapy. Using in vivo pressure-volume catheterization of the right ventricle, we have uncovered key deficiencies in resting and reserve RV function in the SSc-PAH group when compared to idiopathic PAH (IPAH) patients. These studies have uncovered key discoveries with regards to right ventricular-pulmonary arterial (RV-PA) coupling in PAH. In the lab, by studying myofilament function from RV endomyocardial biopsies from these same patients, we have uncovered corresponding deficiencies in myofilament contractility and calcium sensitivity as well. Ongoing work is directed towards determining the underlying mechanism of these findings, which... will hopefully lead to therapeutic applications for RV failure in SSc-PAH.

    Further endeavors are directed towards studying RV failure in other populations, including exercise-induced PH, PH secondary to left-heart disease, and the left ventricular assist device population.

    Basic science investigations span an array of inquiries, such as understanding the basic mechanisms underlying cardiac dyssynchrony and resynchronization in the failing heart, and beneficial influences of nitric oxide/cGMP/protein kinase G and cGMP-targeted phosphdiesterase signaling cascades on cardiac maladaptive stress remodeling. Recently, the latter has particularly focused on the role of phosphodiesterase type 5 and its pharmacologic inhibitors (e.g. sildenafi, Viagra®), on myocyte signaling cascades modulated by protein kinase G, and on the nitric oxide synthase dysregulation coupled with oxidant stress.

    The lab also conducts clinical research and is presently exploring new treatments for heart failure with a preserved ejection fraction, studying ventricular-arterial interaction and its role in adverse heart-vessel coupling in left heart failure and pulmonary hypertension, and testing new drug, device, and cell therapies for heart disease. A major theme has been with the use ...of advanced non-invasive and invasive catheterization-based methods to assess cardiac mechanics in patients.asive and invasive catheterization-based methods to assess cardiac mechanics in patients.

Our Precursors Study has shown that serum cholesterol measured at age 22 years is a predictor for midlife cardiovascular disease, a finding that has influenced policy about cholesterol screening in young adults. We also research health behaviors that lead to hypertension and study how differences in these behaviors affect urban and non-urban populations.

  • Obesity Hypertension Clinic: Reversing the Negative Cardiovascular Effects of Weight (ReNEW)

    Lab Website
    Principal Investigator:
    Tammy Brady, M.D., Ph.D.
    Medicine
    Pediatrics

    Hypertension in children is a major cause of disease, including early onset heart disease. Up to 25% of children who are overweight or obese have hypertension (high blood pressure), and children with obesity are at greater risk for having other cardiovascular disease risk factors such as high cholesterol and diabetes. The ReNEW Clinic at The Johns Hopkins University provides an innovative multidisciplinary approach to the evaluation and treatment of obesity-related hypertension to help prevent and treat cardiovascular disease. This clinic is designed for children with elevated blood pressure (prehypertension and hypertension) and a BMI at or above the 85th percentile. Many children in this clinic are enrolled in a longitudinal registry to help researchers learn how to better care for children with multiple risk factors for heart disease.
