Introduction: The association of chest pain versus dyspnea with demographics, coronary angiographic findings, and outcomes of patients undergoing coronary angiography is unknown.

Material and methods: We studied 1,053 patients who had coronary angiography to investigate the association of chest pain versus dyspnea with demographics, coronary angiographic findings, and outcomes.

Results: Of 1,053 patients, 654 (62%) had chest pain, 229 (22%) had dyspnea, and 117 (11%) had chest pain and dyspnea. Patients with dyspnea were older (p < 0.0001) and had higher serum creatinine (p = 0.0011), lower left ventricular ejection fraction (LVEF) (p < 0.0001), more cardiogenic shock (p = 0.0004), less obstructive coronary artery disease (CAD) (p < 0.0001), less percutaneous coronary intervention (p < 0.0001), and similar 2-year mortality. Stepwise Cox regression analysis showed no significant difference in mortality between chest pain and dyspnea. Significant risk factors for time to death were age (hazard ratio (HR) = 1.07, p < 0.0001), serum creatinine (HR = 1.5, p < 0.0001), body mass index (HR = 0.93, p = 0.005), and obstructive CAD graft (HR = 3.2, p = 0.011).

Conclusions: Patients undergoing coronary angiography presenting with dyspnea were older and had higher serum creatinine, lower LVEF, more frequent cardiogenic shock, less obstructive CAD, and less percutaneous coronary intervention compared to patients presenting with chest pain but similar 2-year mortality.
