Mental and behavioral abnormalities caused by occlusion of the right coronary artery: A case report.

RATIONALE: Mental and behavioral abnormalities are difficult neurological conditions, and the site of the lesion may involve the basal ganglia. Its etiology is varied and requires a detailed differential diagnosis.

PATIENT CONCERNS: An 81-year-old woman had a history of "cerebral infarction" for 5 years. She could walk independently and take care of herself without the assistance of others. This time the chief complaint is generalized fatigue for 4 days and mental and behavioral abnormalities for 1 day.

DIAGNOSES: the right coronary artery occlusion.

INTERVENTIONS: We implanted a drug-eluting stent, then helped her with mechanical ventilation, and implanted a temporary pacemaker.

OUTCOMES: She recovered and can walk alone with a walker.

LESSONS: Right coronary artery infarction often leads to a hypotensive state, shock, and arrhythmias such as bradycardia. Transient ischemic attack or cerebral infarction may be induced if the patient has neck or cerebrovascular lesions. Cranial computed tomography should be performed rapidly in patients presenting with mental and behavioral abnormalities. Simultaneous electrocardiogram (ECG), cardiac ultrasound and myocardial injury marker tests should also be conducted to ensure timely and accurate diagnosis.
