Elective surgery should be postponed until at least 6 months after the event. Untreated or poorly controlled hypertension (diastolic consistently >110 mmHg ) may lead to exaggerated cardiovascular responses during anesthesia. Both hypertension and hypotension can be precipitated which increase the risk of myocardial ischaemia.
