Technical Development of Cardiovascular Magnetic Resonance Imaging (CMR) Using a Low Specific Absorption Rate (SAR) Scanner System

drug called a vasodilator. This helps detect areas of the heart with abnormal blood supply. Scans of the heart are taken before, during, and after they get the medicine. The drug may cause temporary

Comparison of Vasodilator Response of Inhaled Epoprostenol and Inhaled Nitric Oxide

The overarching goal of this study is to examine the acute vasoreactive response to both inhaled nitric oxide and inhaled epoprostenol across both traditionally and non-traditionally interrogated phenotypes in PH, and to further characterize the relationship of vasoreactivity to disease severity and PH phenotype.

The Impact of Sildenafil on the Pulmonary Circulation in Healthy Trained and Untrained Humans

There is emerging evidence suggesting that the pulmonary vasculature and right heart may play a role in the limitation of exercise capacity in healthy individuals. It is well established that aerobic training improves cardiovascular function. While the pulmonary system is integral to the function of the cardiopulmonary system, it has …

The Effect of Hyperbaric Oxygen Treatment in Patients With Osteoradionecrosis.

Osteoradionecrosis (ORN) is a severe delayed radiation-induced injury that can occur in patients whom have been subjected to radiotherapy for head and neck cancer. Hyperbaric oxygen treatment (HBO) is one treatment option. In Sweden it is used in some locations in combination to standard treatment which includes for example antibiotics, …

The Effect of Dopamine on Pulmonary Diffusion and Capillary Blood Volume During Exercise

The purpose of this study is to examine the effect of dopamine infusion and dopamine-2 receptor blockade on pulmonary capillary blood volume, diffusion, and the hemodynamic variables of pulmonary artery pressure, cardiac output, and pulmonary vascular resistance during exercise. Secondarily, this study will examine the effect of dopamine infusion and …
