Panic disorder, anxiety and depression in resistant hypertension--a case-control study

Area of Science:

• Cardiology
• Psychiatry
• Clinical Research

Background:

• Previous suggestions link panic disorder to hypertension and resistance to antihypertensive drugs.
• Investigating the potential role of psychological factors in resistant hypertension is crucial for comprehensive patient care.

Purpose of the Study:

• To compare the prevalence of panic disorder, panic attacks, anxiety, and depression in patients with resistant hypertension versus those with non-resistant hypertension.
• To determine if psychological conditions contribute to drug resistance in hypertension management.

Main Methods:

• A case-control study involving 136 patients with resistant hypertension and matched controls with non-resistant hypertension.
• Utilized self-completed postal questionnaires to assess panic disorder, anxiety, and depression.
• Defined resistant hypertension as uncontrolled blood pressure despite multiple antihypertensive agents.

Main Results:

• No significant differences were found in the prevalence of panic disorder, panic attacks, anxiety, or depression between patients with resistant and non-resistant hypertension.
• Prevalence rates for panic disorder and panic attacks were notably high in both patient groups attending the hypertension clinic.
• Analysis of idiopathic hypertension subgroups also showed no significant differences in panic disorder or panic attack prevalence.

Conclusions:

• Panic disorder, anxiety, and depression do not appear to be implicated in resistance to antihypertensive drug treatment.
• The high prevalence of panic symptoms in hypertensive patients warrants further investigation in the general hypertensive population.
• Further research is needed to understand the complex relationship between panic disorder and hypertension.
