Key result
The annual incidence of mitral stenosis in Korea decreased from 10.3 to 3.6 per 100,000 over 10 years, while increased vitamin K antagonist use was associated with rising intracranial hemorrhage rates.
Why the study?
Mitral stenosis increases the risk of AF and stroke, but large data underlying trends in its incidence, treatment, and outcomes are lacking.
What are the 10-year trends in the incidence, treatment, and outcomes of patients with mitral stenosis in Korea?
Population
42 075 patients diagnosed with mitral stenosis between 2007 and 2016 in Republic of Korea
Comparison
Trends over time across 10 years
Design
Nationwide database study

Declining mitral stenosis incidence may ease rheumatic burden but rising VKA use signals ICH caution; leaves open optimal antithrombotic strategies.
Observational (n=42,075)
What are the 10-year trends in the incidence, treatment, and outcomes of patients with mitral stenosis in Korea?
Kim et al. (2020) conducted an observational in Mitral stenosis (n=42,075). Time period (2007-2016) was evaluated on Trends in the incidence rate and changing patterns of treatment and outcome for stroke, systemic embolism, and intracranial haemorrhage. The annual incidence of mitral stenosis in Korea decreased from 10.3 to 3.6 per 100,000 over 10 years, while increased vitamin K antagonist use was associated with rising intracranial hemorrhage rates.
