Association of Arrhythmias in HIV Patients with Demographics and Comorbidities:
On multivariate analysis, later year of admission had a higher odds ratio (OR) for arrhythmia among HIV patients compared to earlier years (year 2014 vs 2005 OR was 1.391; P<0.0001). Older age was also associated with arrhythmias (OR 1.055; P<0.0001). Female sex was associated with lower odds of arrhythmias (OR 0.689, P<0.0001).
Among comorbidities assessed, congestive heart failure had the strongest correlation with arrhythmias (OR 3.345; P<0.0001), followed by obesity (OR 1.504; P<0.0001), coronary artery disease (OR 1.46; P<0.0001), renal failure (OR1.397; P<0.0001), hypertension (OR 1.205; P<0.0001) and chronic pulmonary disease (OR1.183; P<0.0001).
In addition, cardiogenic shock, cardiac arrest and endotracheal intubation had high OR for arrhythmias (OR 3.18, 2.966 and 2.261 respectively; P<0.0001 for all).
Higher income was associated with arrhythmia-related hospitalization in HIV patients (OR 1.279 in patients with top quartile for income; P<0.0001). Other variables assessed, including type of admission (elective vs. non-elective), day of admission (weekend vs. weekday) and hospital bed size were not strongly associated with arrhythmias. The multivariate predictors of arrhythmias are listed in Table 4.
