Cardiac Magnetic Resonance Imaging (CMR) is an effective tool for evaluating patients with pulmonary arterial hypertension (PAH), according to a new meta-analysis published in JACC: Cardiovascular Imaging.
The study's authors analyzed data from 22 different studies, covering nearly 2,000 patients with pulmonary hypertension. There were 18 clinical worsening events and 8 deaths per 100 patient-years.
The researchers determined CMR to be a powerful tool for predicting clinical worsening in PHA patients, with every 1% decrease in right ventricular ejection fraction associated with a 4.9% increase in the risk of clinical worsening over the next 22 months and a 2.1% increase in the risk of mortality over the next 54 months.
The authors concluded that CMR can effectively predict clinical worsening in PHA patients.
