ConclusionsÄyspnea has become increasingly prevalent among patients referred for cardiac stress testing and is now present among nearly two-fifths of contemporary cohorts referred for stress-rest SPECT-MPI. The adjusted hazard ratio for mortality was higher among patients with dyspnea vs those without dyspnea both among all patients, and within each chest pain subgroup. There was a temporal increase in the prevalence of dyspnea in each age, symptom, and risk factor subgroup. However, there was a stepwise increase in the temporal prevalence of dyspnea, which was present in 25.6% of patients studied between 20, 30.5% of patients studied between 20, and 38.7% of patients studied between 20. The overall prevalence of dyspnea in our cohort was 30.2%. Patients were divided into three temporal groups. Dyspnea was assessed as a single-item question. ![]() We evaluated the prevalence of dyspnea and its relationship to all-cause mortality among 33,564 patients undergoing stress/rest SPECT-MPI between Januand December 31, 2017. ![]() To assess the frequency, change in prevalence, and prognostic significance of dyspnea among contemporary patients referred for cardiac stress testing.
