Key result
Between 2010 and 2019, the proportion of cardiology department deaths due to acute myocardial infarction declined from 61.9% to 46.7%, while deaths from heart failure increased from 11.1% to 25.9%.
Why the study?
Despite efforts to deliver evidence-based care, in-hospital death remains inevitable for some cardiology inpatients, prompting an evaluation of mortality causes in a contemporary cardiology department.

Absolute Event Rate: 46.7% vs 61.9%
Over a 10-year period in a tertiary cardiology department, the proportion of deaths due to acute myocardial infarction significantly declined while deaths due to heart failure increased.
Shifting cardiology mortality from AMI toward HF may inform departmental planning; leaves open causal drivers and targeted interventions.
Despite the efforts to deliver the best evidence-based care, in-hospital death is an inevitable event among some patients hospitalized in cardiology departments. We conducted a retrospective evaluation of mortality events from inpatient admissions to the cardiology department between 2010 and 2019. Data were collected from morbidity and mortality meeting presentations that evaluated comorbidities, medical history, treatments, and causes of death for the overall cohort and according to age group and sex. There were 1182 registered deaths. The most common causes of death among patients were acute myocardial infarction (AMI, 53.0%), heart failure (HF, 11.7%), cardiac arrest (CA, 6.6%), HF with complication/defined cardiomyopathy (6.3%), and sepsis (4.4%). We observed a decline in deaths from AMI from 61.9% in 2010 to 46.7% in 2019, while there was a clear increase in deaths from HF (11.1% in 2010 to 25.9% in 2019). Compared to patients ≥65 years, younger patients were more likely to have died from CA (15.7% vs. 4.3%, p < 0.001) and other cardiac reasons (3.0% vs. 0.4%, p < 0.001). The majority of deaths were due to AMI, HF, and CA. We observed a significant declining trend in the proportion of deaths due to AMI in recent years, with an increase in deaths due to HF.

Kwok et al. (2023) conducted an observational in In-hospital death in cardiology department (n=1,182). Admission in 2019 vs. Admission in 2010 was evaluated on Proportion of deaths due to acute myocardial infarction. Between 2010 and 2019, the proportion of cardiology department deaths due to acute myocardial infarction declined from 61.9% to 46.7%, while deaths from heart failure increased from 11.1% to 25.9%.
