Although epidemiologic studies have shown the impact of height on occurrence and/or prognosis of cardiovascular diseases, the underlying mechanism is unclear. In addition, the relation in patients with ST-segment elevation myocardial infarction (STEMI) who underwent primary percutaneous coronary intervention (PCI) remains unknown. We sought to assess the influence of height on outcomes of patients with acute STEMI undergoing primary PCI and to provide a pathophysiological explanation. ⋯ The first-tertile group showed the worst MACCE-free survival (p = 0.035), and most cases of MACCE were HF (n, 17 [3%] vs 6 [1%] vs 2 [0%], p = 0.004). On post-PCI echocardiography, left atrial volume and early diastolic mitral velocity to early diastolic mitral annulus velocity ratio showed an inverse relation with height (p <0.001 for all) despite similar left ventricular ejection fraction. In conclusion, short stature is associated with occurrence of HF after primary PCI for STEMI, and its influence is prominent in aged male patients presumably for its correlation with diastolic dysfunction.

Direct oral anticoagulants (DOACs) have been used in clinical practice in the United States for the last 4 to 6 years. Although DOACs may be an attractive alternative to warfarin in many patients, long-term outcomes of use of these medications are unknown. We performed a propensity-matched analysis to report patient important outcomes of death, stroke/transient ischemic attack (TIA), bleeding, major bleeding, and dementia in patients taking a DOAC or warfarin. ⋯ In the AF multivariable model patients taking DOAC were 43% less likely to develop stroke/TIA/dementia (hazard ratio 0.57 [CI 0.17, 1.97], p = 0.38) than those taking warfarin. Our community-based results suggest better long-term efficacy and safety of DOACs compared with warfarin. DOAC use was associated with a lower risk of cerebral ischemic events and new-onset dementia.
