Table 2.
Frequencies of various categorical variables among 85 episodes of definite infective endocarditis.a
| Baseline parameter | Frequency, n (%) |
|---|---|
| Thrombocytopeniab | 12 (14.1%) |
| Hypoalbuminemiab (N = 83) | 52 (62.7%) |
| Hyponatremiab | 54 (63.5%) |
| Diabetes mellitus | 10 (11.8%) |
| Smokerc | 22 (25.9%) |
| Vegetation size >10 mm | 58 (73.4%) |
| Aortic valve involvement | 27 (34.2%) |
| Mitral valve involvement | 46 (57.5%) |
| New-onset significant valvular dysfunctiond | 60 (70.6%) |
| Cardiac abscess | 8 (9.4%) |
| Blood culture positive | 51 (60%) |
| Prosthetic valve involvement | 16 (18.8%) |
| Staphylococcus aureus infection (N = 54) | 26 (48.1%) |
| NYHA class I/II | 47 (55.3%) |
| NYHA class III/IV | 38 (44.7%) |
Categorical variables are expressed as number (percentage) and the total sample size is N = 85. For hypoalbuminemia data is available for 83 patients. The percentage of S. aureus infection is calculated out of 54 episodes with a positive blood culture.
Thrombocytopenia is defined as a platelet count less than 1,00,000/μl; Hyponatremia is defined as S. sodium <135 meq/l; hypoalbuminemia is defined as S. albumin <3.5 mg/dl.
A smoker is defined as a person with a lifetime history of smoking >100 cigarettes.
New-onset significant valvular dysfunction is defined as a any new detection of moderate or more valvular regurgitation or any form of prosthetic valve dysfunction.
