Patrick is a 78-year-old male who has worsening of his left-sided heart failure and COPD.
He is very tired, coughs regularly, and he suffers from dyspnoea. His legs are swollen from the knee down, and he walks slowly.
His current observations and body size measurements are: blood pressure 135/85 mmHg; heart rate 155 bpm, weight 95 kg, height 180 cm, waist circumference 104 cm.
His previous medical history is:
o Smoking from age 20 to approximately 60; he quit smoking in his early 60s. o Myocardial infarction following occlusion of a branch of his left coronary artery, age 68
Patrick’s fasting blood test results include:
