In Framingham Heart Study participants, cardiovascular risk factors in participants diagnosed with atrial fibrillation (AF) and in referents free of AF, matched on age and follow-up time.
| Diagnosed with AF, survived 30 days thereafter (n = 336) | Time- and age-matched participants without AF (n = 336) | |

| Current smoker | 16% | 3% |
| Impaired glucose or diabetes | 20% | 10% |
| Systolic blood pressure, mmHg, mean (SD) | 137 (23) | 135 (18) |

SD: standard deviation; HDL: high-density lipoprotein; MI: myocardial infarction.
a
Hypertension defined by elevated clinic blood pressure or by antihypertensive medication use plus physician diagnosis of hypertension.
b
Medicare-enhanced data are not presented in these cells due to a small sample size.
