Cohort study

Clinical and Prognostic Relevance of Cardiac Wasting in Patients With Advanced Cancer

J Am Coll CardiolPublished

  • Prospective cohort study

Authors' conclusion

Low LV mass is associated with poor functional status and increased all-cause mortality in cancer.

Study context

Population
Patients with mostly advanced, active cancer without significant CVD or infection; controls of similar age and sex
Participants
300 / 60 / 60
Exposure
Cancer patients vs healthy controls vs chronic HF patients
  • Cancern = 300
  • Healthy controln = 60reference
  • Heart failuren = 60

Main finding

As reported in the abstract

LV mass (transthoracic echocardiography)
Lower left ventricular (LV) mass in cancer than controls or HF
P < 0.001

Observational data: associations, not effects.

Further findings

LV mass, cancer patients with cachexia

LV mass lowest in cancer patients with cachexia
153 ± 42 g
  • P < 0.001

Low LV mass and previous cardiotoxic anticancer therapy

Low LV mass independent of previous cardiotoxic anticancer therapy

All-cause mortality, cancer patients · mean follow-up 16 months

Deaths
149
1-year all-cause mortality
43% (95% CI: 37%-49%)

Change in LV mass on second echocardiogram (90 cancer patients) · 122 ± 71 days

LV mass decline
9.3% ± 1.4%
  • P < 0.001

Stroke volume and resting heart rate in cancer patients with cardiac wasting

Stroke volume decreased
P < 0.001
Resting heart rate increased
P = 0.001

LV mass as prognostic marker

LV mass and LV mass adjusted for height squared independent prognostic markers
P < 0.05
Adjustment for body surface area masked the survival impact

Functional status and physical performance

LV mass below prognostic cutpoints associated with reduced functional status and lower physical performance
