For each condition, we examined trends in adjusted rates of hospitalization per patient-year and, for each hospitalization, rates of 30-day mortality, 30-day readmission, and 1-year mortality overall and by demographic subgroups and regions. Rates of adjusted hospitalization declined for cardiovascular conditions (38.0% for 2011 compared with 1999 [95% confidence interval (CI), 37.2\u201338.8] for myocardial infarction, 83.8% [95% CI, 83.3\u201384.4] for unstable angina, 30.5% [95% CI, 29.3\u201331.6] for heart failure, and 33.6% [95% CI, 32.9\u201334.4] for ischemic stroke compared with 10.2% [95% CI, 10.1\u201310.2] for all other conditions). Adjusted 30-day mortality rates declined 29.4% (95% CI, 28.1\u201330.6) for myocardial infarction, 13.1% (95% CI, 1.1\u201323.7) for unstable angina, 16.4% (95% CI, 15.1\u201317.7) for heart failure, and 4.7% (95% CI, 3.0\u20136.4) for ischemic stroke. There were also reductions in rates of 1-year mortality and 30-day readmission and consistency in declines among the demographic subgroups.<\/jats:p>\n          <\/jats:sec>\n          <jats:sec>\n            <jats:title>Conclusions\u2014<\/jats:title>\n            <jats:p>Hospitalizations for acute cardiovascular disease and stroke from 1999 through 2011 declined more rapidly than for other conditions.
