Abstract P104: Oxygen Drastically Increases Cardiac Output Without Changing Mean Pulmonary Arterial Pressure in a Patient With Severe, Progressive Pulmonary Hypertension Session Title: Onsite Poster Competition I With Reception
Conclusion: Our patient had no significant change in mPAP facing oxygen-induced decrease in PVR. Instead, there was a marked increase in RV CO explainable only by an increase in RV SV facing decreased RV afterload, as HR decreased with oxygen. These findings are consistent with the patient’s class 1 exercise capacity despite having severe PH, indicating an ability to increase CO with activity and suggesting a positive response to medications and better prognosis. Our case shows the importance of assessing hemodynamic data in the workup and management of PH. We propose using TTE assessment of CO coupled with 100% oxygen a...

Selective Heart Rate Reduction With Ivabradine Increases Central Blood Pressure in Stable Coronary Artery Disease Clinical Trials
In conclusion, the decrease in HR with ivabradine was associated with an increase in central systolic pressure, which may have antagonized possible benefits of HR lowering in coronary artery disease patients. Clinical Trials—URL: http://www.clinicaltrials.gov. Unique identifier NCT01039389.
