Background
Sinus tachycardia in cancer reflects significant multi-system organ stressor and disease, with sparse literature describing its clinical significance. We assessed cardiovascular (CV) and mortality prognostic implications of sinus tachycardia in cancer patients.
Methods
We conducted a case-control study of 622 cancer patients at a U.S. urban medical center from 2008 to 2016. Cases had ECG-confirmed sinus tachycardia (heart rate [HR] ≥ 100 bpm) in ≥ 3 different clinic visits within 1 year of cancer diagnosis excluding history of pulmonary embolism, thyroid dysfunction, left ventricular ejection fraction < 50%, atrial fibrillation/flutter, HR > 180 bpm. Adverse CV outcomes (ACVO) were heart failure with preserved ejection fraction (HFpEF), HF with reduced EF (HFrEF), hospital admissions for HF exacerbation (AHFE), acute coronary syndrome (ACS). Regression analyses were conducted to examine the effect of sinus tachycardia on overall ACVO and survival.
Results
There were 51 cases, age and sex-matched with 571 controls (mean age 70 ± 10, 60.5% women, 76.4% Caucasian). In multivariate analysis over a 10-year follow-up period, sinus tachycardia (HR ≥ 100 vs. < 100 bpm) was an independent predictor of overall ACVO (OR 2.8, 95% CI: 1.4 -5.5; p = 0.006). There was increased incidence of HFrEF (OR 3.3, 95% CI: 1.6- 6.5; P= 0.004) and AHFE (OR 6.3, 95% CI: 1.6-28; P = 0.023), but not HFpEF or ACS (p>0.05) compared with controls. Sinus tachycardia was a significant predictor of overall mortality after adjusting for significant covariates (HR 2.9, 95% CI 1.8-5; p<0.001).
Conclusion
Independent of typical factors that affect cardiovascular disease, sinus tachycardia around the time of cancer treatment is associated with increased ACVO and mortality in cancer patients at 10 years of follow-up.
