Association of marital status with takotsubo syndrome (broken heart syndrome) among adults in the United States

Table 2 Adjusted estimates for the association of marital status with takotsubo syndrome by acute myocardial infarction and non-cardiovascular disease controls, National Hospital Discharge Survey 2006-2010¹

Marital status	Cases (n = 59)	AMI controls (n = 295)	Non-CVD controls (n = 295)	Odds ratios (95%CI) for AMI controls	Odds ratios (95%CI) for non-CVD controls
Single	10	53	40	1	1
Married	23	133	126	0.69 (0.63-0.75)	0.86 (0.79-0.93)
Widowed	16	76	93	1.09 (1.01-1.19)	1.14 (1.05-1.23)
Separated/divorced	10	33	36	1.27 (1.16-1.39)	1.32 (1.21-1.45)
Married	23	133	126	1	1
Not married	36	162	169	1.66 (1.58-1.75)	1.40 (1.34-1.46)

¹Each case was matched to five controls based on age, sex, year of takotsubo cardiomyopathy diagnosis and bed size of hospital. Adjusted for age, sex, year of TTS diagnosis, bed size of hospital, race, type of health insurance, smoking status, obesity, hypertension, dyslipidemia, diabetes and chronic obstructive pulmonary disease. AMI: Acute myocardial infarction; CI: Confidence interval; CVD: Cardiovascular disease.
