Abstract

OBJECTIVE: To evaluate the impact of pulmonary hypertension (PH) on percutaneous coronary intervention (PCI) outcomes and 30-day all-cause readmissions by analyzing a national database.

METHODS: We queried the 2014 National Readmissions Database to identify patients undergoing PCI using International Classification of Diseases, Ninth Revision, Clinical Modification codes. These patients were then subcategorized based on the coded presence or absence of PH and further analyzed to determine the impact of PH on clinical outcomes, health care use, and 30-day readmissions.

RESULTS: Among 599,490 patients hospitalized for a PCI in 2014, 19,348 (3.2%) had concomitant PH. At baseline, these patients were older with a higher burden of comorbidities. Patients with PH had longer initial hospitalizations and higher 30-day readmission rates and mortality than their non-PH counterparts. This was largely driven by cardiac causes, most commonly heart failure (20.3% vs 9.0%, P

CONCLUSION: Patients with PH undergoing PCI are a high-risk group in terms of mortality and 30-day readmission rates. Percutaneous coronary intervention in patients with PH is associated with higher rates of recurrent heart failure and non-ST-segment elevation myocardial infarction, rather than recurrent coronary events or ST-segment elevation myocardial infarction. This perhaps indicates a predominance of demand ischemia and heart failure syndromes rather than overt atherothrombosis in the etiology of chest pain in these patients.
