The Gender Perspective Within the OFRECE Study: Differences in Health Care Among Patients Consulting for Chest Pain and/or Palpitations.

ABSTRACT

INTRODUCTION AND OBJECTIVES: To analyze differences between sexes in the clinical management of patients presenting with symptoms of chest pain and/or palpitations within a population-based study. METHODS: The OFRECE study included a random sample of 8400 individuals from the Spanish population aged 40 years and older; 1132 (13.5%) had previously consulted for chest pain and 1267 (15.1%) had consulted for palpitations and were included in the present study. We calculated both the crude and adjusted odds ratios (OR) of undergoing certain tests and the results of consultations by sex. Adjustment was performed by classic cardiovascular risk factors, a personal history of cardiovascular disease, and a diagnosis of stable angina or atrial fibrillation confirmed in the OFRECE study in each case. RESULTS: No differences were observed in history of consultation for chest pain between women and men (13% vs 14.1%; P=.159) but differences were found in palpitations (19% vs 10.4%, respectively; P <.001). Women who had previously consulted for chest pain underwent fewer echocardiograms (32.5% vs 45.3%, respectively; P <.001), were less frequently referred to a cardiologist (49.1% vs 60.1%; P <.001), were less often admitted to hospital (20.1% vs 39.4%; P <.001), and less frequently received a confirmed diagnosis (60.9 vs 71, 9; P <.001). After full adjustment, all differences decreased and become nonsignificant echocardiograms adjusted OR, 0.81; 95%CI, 0.60-1.09; referral to a cardiologist adjusted OR, 0.86; 95%CI, 0.63-1.16; hospital admission adjusted OR, 0.76; 95%CI, 0.54-1.09). For palpitations, crude differences were smaller and all became nonsignificant after adjustment. CONCLUSIONS: This study does not confirm the existence of sex-related bias in the management of chest pain and palpitations. However, such bias cannot be completely ruled out in diagnoses confirmed within the OFRECE study, which might limit its ability to detect sex-related differences in health care.
