Key result
Resting Doppler coronary flow velocity during routine echocardiography predicts short-term death and MI in elderly patients.
Why the study?
Risk assessment of CAD in the elderly is challenging due to physical and clinical limitations, making non-invasive resting Doppler coronary flow velocity assessment a potentially helpful prognostic tool.
Does Doppler echocardiographic coronary flow velocity assessment at rest predict short-term prognosis in elderly patients?

Does Doppler echocardiographic coronary flow velocity assessment at rest predict short-term prognosis in elderly patients?
Doppler coronary flow velocity assessment at rest during routine echocardiography may be a feasible and valuable tool for short-term prognostic assessment in elderly patients.
May support short-term prognosis assessment in elderly patients during routine echo; hypothesis-generating, requiring prospective validation before practice change.
BACKGROUND: Atherosclerosis and coronary artery disease (CAD) are a common condition and cause of death in the elderly population. There are difficulties with risk assessment in the elderly as the objectification of their symptomatic status can be challenging due to neuromuscular weakness, physical deconditioning or neurological, orthopaedic, peripheral vascular, or respiratory limitations. Non-invasive coronary artery velocity assessment by Doppler method at rest could be helpful in the elderly population. To evaluate the prognostic role of coronary artery ultrasound assessment in a non-selected elderly population in everyday clinical practice. METHODS: One hundred forty-five patients, aged ≥75years (99 women; 80 ± 4 years), formed the study group. Left coronary artery flows were scanned in addition to conventional echocardiography. During a median follow-up of 26 months, 16 deaths and 2 non-fatal MI occurred. CONCLUSION: Doppler CFL scanning during routine echocardiography is a feasible and valuable tool for assessment of short-term prognosis in elderly patients.

Zagatina et al. (2022) conducted an observational in Coronary artery disease (n=145). Doppler echocardiographic coronary flow velocity assessment at rest was evaluated on Death and non-fatal myocardial infarction (p=<0.0001). Doppler coronary flow velocity scanning at rest during routine echocardiography is a feasible and valuable tool for assessing short-term prognosis in elderly patients (P<0.0001).
