Mr. Heart is a 70-year-old man who comes to your office to establish care. He has a history of HIV. His last CD4 was 500 cells/mm3 with an undetectable viral load. He takes atazanavir, ritonavir, emtricitabine and tenofovir. Otherwise, he has a history of hypertension, hyperlipidemia, and diabetes. His other medications include lisinopril 20 mg daily, simvastatin 20 mg daily, and metformin 1000 mg daily.
Mr. Heart mentions that one of his best friends just had a heart attack, which scared him. He wants to do everything he can to prevent heart disease.
1. How does the prevalence rate of cardiovascular disease in HIV-infected patients differ from that in the uninfected?
2. What are the risk factors for cardiovascular disease in HIV patients? What are the traditional risk factors (ones also found in the uninfected)? What are risk factors related to HIV or its treatments?
3. What other questions would you ask Mr. Heart?
Mr. Heart states he is adherent with all of his medications, although he has not seen a doctor in about a year. His father died of a heart attack at age 50, while his mother died at age 70 from a stroke. She had hypertension and diabetes.
He used to snort cocaine but quit 15 years ago, after which he picked up tobacco smoking. He now smokes 1 pack per day. He drinks a glass of wine with dinner everyday.
Mr. Heart rarely cooks. He usually eats take-out hamburgers or pasta. He tires easily because of his weight and rarely exercises.
On exam, his pulse is 78, BP 160/95, oxygen saturation 99% on room air. His BMI is 40 kg/m2. There are no abnormal findings on exam. His point-of-care fasting glucose was 85 mg/dl.
4. What cardiovascular risk factors does Mr. Heart have? How would you estimate cardiovascular risk for Mr. Heart based on his risk factor profile?
5. How would you modify Mr. Heart’s risk factors?
6. What workup would you order and how often would you order them?
On labs, his HbA1C is 6.5%. His total cholesterol is 195, HDL 53, LDL 110, triglycerides 162.
His BMP is normal and you increase lisinopril from 20 mg daily to 40 mg daily.
7. Is lipid-lowering treatment indicated for Mr. Heart? If yes, would you continue the current regimen of simvastatin 20 mg daily?
8. Does Mr. Heart have hypertriglyceridemia? How would you manage it? What if his triglyceride level is more than 500 mg/dl?
9. What would you do with Mr. Heart’s ART regimen? What regimen would you pick if he were treatment-naïve considering he has hyperlipidemia?
