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.
