Final answer:
It is true that additional diagnoses should be assigned if a patient has both ischemic heart disease and hypertension, as they are separate conditions that require individual treatment and management strategies.
Step-by-step explanation:
True, additional diagnoses should be assigned if a patient has ischemic heart disease and also hypertension as these are distinct medical conditions that can occur concomitantly. Each condition can affect the patient differently, and appropriate diagnoses and treatment plans for both are crucial to manage the patient's overall health. Ischemic heart disease is often caused by atherosclerosis, which can lead to angina or myocardial infarction (heart attack). Hypertension, or high blood pressure, is a significant risk factor for cardiovascular disease and other complications such as kidney failure and stroke. It is essential in medical practice to clearly document all comorbid conditions to ensure comprehensive patient care.
