Only primary hospitalized diagnoses with clinical relevance and an incidence >1% are included. Values are percents unless otherwise stated. The following International Classification of Diseases-9th Edition-Clinical Modification (ICD-9-CM) codes were used: myocardial infarction (ICD-9-CM 410), other acute ischemic heart disease (ICD-9-CM 411), angina (ICD-9-CM 413), atrial fibrillation (ICD-9-CM 427.3), ventricular arrhythmias (ICD-9-CM 427.1/4/5), chronic obstructive pulmonary disease (COPD) (ICD-9-CM 496), cerebrovascular disease (ICD-9-CM 433 to 435), and renal disease (ICD-9-CM 403, 404, 584, 585).

HF = heart failure.
