What is the best course of action for a 61-year-old male patient with hypertension, currently taking Lipitor (atorvastatin) 40 mg, baby aspirin (acetylsalicylic acid) 81 mg, and losartan, who presents with lightheadedness and has a history of carotid artery disease?

From the Guidelines

The best course of action for this 61-year-old male patient with hypertension and lightheadedness is immediate evaluation for carotid artery stenosis and possible orthostatic hypotension, with a focus on adjusting the current medication regimen to prevent excessive blood pressure reduction, as recommended by the 2024 ESC guidelines for the management of elevated blood pressure and hypertension 1. The patient should be scheduled for urgent carotid ultrasound to assess the severity of carotid disease and determine if there is critical stenosis requiring intervention.

• Blood pressure measurements should be taken in both sitting and standing positions to evaluate for orthostatic hypotension, which could be contributing to lightheadedness.
• The current medication regimen should be reviewed, particularly the losartan dosage, as it may need adjustment if it's causing excessive blood pressure reduction.
• Laboratory tests including complete blood count, electrolytes, renal function, and blood glucose should be ordered to rule out other causes of lightheadedness. The patient should continue taking atorvastatin 40 mg and aspirin 81 mg as these medications are important for secondary prevention in carotid artery disease, as outlined in the 2011 ASA/ACCF/AHA/AANN/AANS/ACR/ASNR/CNS/SAIP/SCAI/SIR/SNIS/SVM/SVS guideline on the management of patients with extracranial carotid and vertebral artery disease 1 and the 2011 guidelines for the prevention of stroke in patients with stroke or transient ischemic attack 1. However, the timing of losartan administration might be adjusted to evening if orthostatic symptoms occur primarily in the morning. Lightheadedness in a patient with carotid disease requires prompt attention as it could indicate cerebral hypoperfusion from worsening stenosis or a medication side effect, either of which could precede a more serious cerebrovascular event. According to the 2024 ESC guidelines, upfront low-dose combination therapy is recommended in persons with hypertension, with the potential advantages of fewer side effects and swifter blood pressure control being important for long-term adherence 1. In this case, the patient is already taking losartan, an angiotensin II receptor blocker, which is one of the recommended first-line BP-lowering medications, and atorvastatin, which is important for secondary prevention in carotid artery disease. The focus should be on adjusting the current medication regimen to prevent excessive blood pressure reduction and ensuring that the patient's blood pressure is well-controlled to reduce the risk of stroke and other cerebrovascular events.

Patient Advice

To advise the 61-year-old male patient with hypertension, currently taking Lipitor (atorvastatin) 40 mg, baby aspirin (acetylsalicylic acid) 81 mg, and losartan, who presents with lightheadedness and has a history of carotid artery disease, consider the following points:

• The patient's current medication regimen includes atorvastatin, aspirin, and losartan, which are commonly used to manage hypertension and prevent cardiovascular events 2, 3, 4, 5.
• The dose of aspirin (81 mg) is within the recommended range for secondary prevention of atherosclerotic cardiovascular disease (ASCVD) 2.
• High-dose atorvastatin (40 mg) combined with aspirin may be effective in reducing inflammatory cytokine levels and carotid plaque area, but may also increase the risk of blood glucose abnormalities 3.
• Losartan has been shown to reduce carotid artery hypertrophy and improve vascular remodeling, which may be beneficial for patients with carotid artery disease 4, 5.
• The patient's lightheadedness may be related to their hypertension or carotid artery disease, and further evaluation and monitoring may be necessary to determine the cause and appropriate treatment.

Medication Management

Consider the following points when managing the patient's medications:

• Continue the current dose of aspirin (81 mg) for secondary prevention of ASCVD, as there is no significant difference in safety and effectiveness between 81 mg and 325 mg doses 2.
• Monitor the patient's blood glucose levels regularly, as high-dose atorvastatin (40 mg) may increase the risk of blood glucose abnormalities 3.
• Continue losartan to manage hypertension and reduce carotid artery hypertrophy, as it has been shown to be effective in improving vascular remodeling 4, 5.
• Consider the patient's overall cardiovascular risk profile and adjust their medication regimen as needed to minimize the risk of cardiovascular events.

Lifestyle Modifications

Consider the following lifestyle modifications to help manage the patient's hypertension and reduce their cardiovascular risk:

• Encourage the patient to adhere to a Mediterranean-type diet, which has been shown to be beneficial for cardiovascular health 6.
• Recommend regular physical activity and stress management techniques to help reduce blood pressure and improve overall cardiovascular health.
• Encourage the patient to quit smoking, if applicable, as smoking is a significant risk factor for cardiovascular disease.
