Urolithiasis is a common disease in modern society. Several studies had revealed that urolithiasis is associated with many systemic diseases. We aimed to use the National Health Insurance Research Database (NHIRD) to investigate the relationship of urolithiasis and acute myocardial infarction (AMI).
Materials and Methods:
Patients with the diagnosis of urolithiasis (ICD-9-CM codes 592.0, 592.1, 592.9) before Jan 1, 2003 were retrieved from the NHIRD’s Longitudinal Health Insurance Database 2005 as the case group. Patients without urolithiasis were matched with 1:4 ratio regarding to sex, age and comorbidities as control group. Both groups were followed till myocardial infarction were encountered (ICD-9-CM codes 410, 411, 412, 413, 414, or 440) or till the end of 2012.
Total 37,052 cases and 148,209 controls were inducted into this study. The risk of AMI was higher among patients with urolithiasis (adjusted hazard ratio [aHR] 1.07, 95% confidence interval [CI] 1.03–1.13). We detected a significant association between urinary calculi and intubation (aHR 1.53, 95% CI 1.36–1.73), intensive care unit treatment (aHR 1.22, 95% CI 1.13–1.32), heart failure (aHR 1.59, 95% CI 1.42–1.78), shock (aHR 1.53, 95% CI 1.32–1.77) and arrhythmias (aHR 1.18, 95% CI 1.06–1.33). Patients with kidney stones have the highest risk of AMI.
Urolithisis is associated with higher risks of AMI and several complications of AMI. Treating urolithiasis more aggressively is recommended for patients with comorbidities related to AMI.
