Multivariable association between patient characteristics and referral for echocardiography in 683 patients with a GP’s diagnosis of heart failure
| Adjusted odds ratio (95 % CI) | |
|---|---|
| Age, per year | 0.98 (0.96 to 0.99) |
| Male sex | 1.19 (0.85 to 1.65) |
| Hypertension | 1.01 (0.74 to 1.39) |
| Angina pectoris | 1.00 (0.66 to 1.52) |
| Prior myocardial infarction | 1.73 (1.19 to 2.49) |
| Atrial fibrillation | 1.35 (0.98 to 1.86) |
| Diabetes mellitus | 0.91 (0.64 to 1.29) |
| COPD | 1.02 (0.69 to 1.52) |
| Renal insufficiency (eGFR<30 mL/min/1.73 m2) | 1.23 (0.70 to 2.16) |
| Mild renal impairment (eGFR between 30 mL/min/1.73 m2 and <60 mL/min/1.73 m2) | 1.04 (0.73 to 1.47) |
| Natriuretic measurements performed | 1.29 (0.94 to 1.79) |
| Diuretic prescription | 1.21 (0.84 to 1.73) |
| ACE inhibitor or ARB prescription | 1.42 (1.03 to 1.96) |
| Beta-blocker prescription | 1.04 (0.75 to 1.44) |
ACE inhibitor = angiotensin-converting enzyme inhibitor. ARB = angiotensin receptor blocker. COPD = chronic obstructive pulmonary disease. eGFR = the calculated renal flow according to the modification of diet in renal diseases (MDRD) formula.
