Key result
An older adult with undiagnosed coronary artery disease and hypovolemia experienced a severe systolic blood pressure drop to the 50s during general anesthesia induction.
Why the study?
Anesthetics reduce cardiac functions and lower blood pressure, potentially causing excessive blood pressure reduction during general anesthesia in older adults with conditions such as dehydration or coronary artery disease.
Does achieving normovolemia prevent severe hypotension during general anesthesia induction in a patient with severe coronary artery disease?

Does achieving normovolemia prevent severe hypotension during general anesthesia induction in a patient with severe coronary artery disease?
Thorough cardiac evaluation and maintenance of normovolemia are crucial for safe general anesthesia induction in older adults with severe coronary artery disease.

Requires vigilance against severe hypotension in hypovolemic CAD patients during anesthesia; case report leaves open need for targeted protocols.
Anesthetics reduce cardiac functions and lower blood pressure (BP), potentially causing excessive BP reduction in dehydrated patients or those with heart conditions, such as coronary artery disease (CAD). Considering the increased prevalence of cardiovascular disease with age, anesthesiologists must be cautious about BP reduction during general anesthesia in older adults. In the present case, an undiagnosed CAD patient in a hypovolemic state experienced a significant systolic blood pressure drop to the 50s during propofol and sevoflurane anesthesia. Despite the use of vasopressors, excessive hypotension persisted, leading to anesthesia suspension. Subsequent cardiac examinations, including computed tomography heart angio and calcium score, and coronary angiogram, revealed a near total occlusion of the left main coronary artery and the formation of collateral circulation. After 5 days of hydration and anticoagulation medications and confirmation of normovolemic state, general anesthesia was attempted again and successfully induced; a normal BP was maintained throughout the surgery. Thus, it is important to conduct a thorough cardiac evaluation and maintain normovolemia for general anesthesia in older adults.

Young et al. (2024) conducted a case report in Undiagnosed coronary artery disease and hypovolemia (n=1). General anesthesia induction (propofol and sevoflurane) was evaluated on Systolic blood pressure drop. An older adult with undiagnosed coronary artery disease and hypovolemia experienced a severe systolic blood pressure drop to the 50s during general anesthesia induction.
