What is the best treatment approach for a 50-year-old male patient with hypertension (HTN), hyperlipidemia, impaired glucose regulation (A1C of 5.9), and overweight, who has had adverse reactions to lisinopril (Angiotensin-Converting Enzyme Inhibitor), losartan (Angiotensin II Receptor Blocker), and amlodipine (Calcium Channel Blocker)?

From the Guidelines

For this 50-year-old male with multiple cardiovascular risk factors and medication intolerances, a thiazide diuretic such as chlorthalidone (12.5-25 mg daily) would be the best initial treatment approach for hypertension, as recommended by the 2024 ESC guidelines for the management of elevated blood pressure and hypertension 1. Given his adverse reactions to first-line agents like lisinopril, losartan, and amlodipine, and considering the latest guidelines, chlorthalidone is a suitable option. Additionally, for his impaired glucose regulation (A1C of 5.9) and overweight, lifestyle modifications are crucial, including a DASH diet, sodium restriction, regular physical activity, and weight loss targeting 5-10% of body weight, as suggested by the 2007 guidelines for the management of arterial hypertension 1 and the 2019 standards of medical care in diabetes 1. Considering his hyperlipidemia, with a total cholesterol of 176, triglycerides of 309, HDL of 40, and LDL of 74, management of dyslipidemia should also be addressed through lifestyle changes and potentially statin therapy, depending on his overall cardiovascular risk assessment. The use of GLP-1 receptor agonists or metformin for weight loss and insulin resistance could be considered, but the primary approach should focus on lifestyle modifications and the management of his hypertension and dyslipidemia. Close monitoring of his blood pressure, metabolic panels, and lipid profiles is necessary to adjust his treatment plan as needed. This approach prioritizes the management of his hypertension, dyslipidemia, and impaired glucose regulation, while also addressing his overweight status, ultimately aiming to reduce his cardiovascular risk and improve his quality of life. Key points to consider in his management include:

• Regular monitoring of blood pressure and adjustment of antihypertensive medication as needed
• Lifestyle modifications for weight loss and management of dyslipidemia and impaired glucose regulation
• Consideration of pharmacological therapy for dyslipidemia and impaired glucose regulation if lifestyle modifications are insufficient
• Regular assessment of his renal function and electrolyte levels, especially if initiating or adjusting medications that may affect these parameters.

From the Research

Treatment Approach for Hypertension and Hyperlipidemia

• The patient has a history of adverse reactions to lisinopril, losartan, and amlodipine, making it necessary to consider alternative treatment options for hypertension.
• Chlorthalidone has been shown to be an effective diuretic and blood-pressure-lowering agent, with a unique advantage in its capacity to improve cardiovascular outcomes in patients with hypertension 2.
• A study published in The New England Journal of Medicine found that chlorthalidone therapy improved blood-pressure control at 12 weeks in patients with advanced chronic kidney disease and poorly controlled hypertension 3.

Treatment Approach for Impaired Glucose Regulation and Weight Loss

• The patient's A1C level is 5.9, indicating impaired glucose regulation, and they are overweight, making it necessary to consider treatment options that can help with weight loss and improve insulin sensitivity.
• GLP-1 receptor agonists have been shown to be effective in reducing A1C and weight, with a low risk of hypoglycemia 4.
• A review of head-to-head clinical studies found that all GLP-1 receptor agonists are effective therapeutic options for reducing A1C, but differences exist in terms of magnitude of effect on A1C and weight, as well as frequency of adverse effects 4.
• Liraglutide, a GLP-1 receptor agonist, has been shown to moderately lower blood pressure due to increased natriuresis and RAAS inhibition, and may be a suitable option for patients with impaired glucose regulation and overweight or obesity 5, 6.

Potential Treatment Combination

• Considering the patient's history of adverse reactions to previous medications, a potential treatment combination could be chlorthalidone for hypertension and a GLP-1 receptor agonist, such as liraglutide, for weight loss and improved insulin sensitivity.
• This combination may help to improve blood pressure control, reduce weight, and improve cardiovascular outcomes, while also addressing the patient's impaired glucose regulation 2, 3, 4, 5, 6.
