Summary
Medication adherence in acute aortic dissection (AAD) survivors was 64%, with non-adherence linked to chest pain recurrence. Clinicians should emphasize antihypertensive therapy importance and assess patient forgetfulness.
Area of Science:
- Cardiovascular Medicine
- Medical Outcomes Research
Background:
- Beta-blockers improve survival in acute aortic dissection (AAD) types A and B.
- Calcium channel blockers selectively benefit type B AAD patients.
- Limited data exists on medication adherence in AAD survivors.
Purpose of the Study:
- To assess medication adherence among patients who survived acute aortic dissection.
- To identify factors influencing medication adherence in AAD survivors.
Main Methods:
- Cross-sectional, survey-based study of AAD survivors from a single medical center.
- Utilized data from the International Registry of Acute Aortic Dissection (IRAD).
- Assessed medication adherence using the 4-item Morisky scale.
Main Results:
- 64% of AAD survivors demonstrated medication adherence based on the Morisky scale.
- Non-adherence (Morisky score ≥1.0) was associated with increased chest pain recurrence at one year.
- Forgetfulness and carelessness were reported by 33% and 8% of patients, respectively.
Conclusions:
- A significant proportion of AAD survivors exhibit suboptimal medication adherence.
- Clinicians should reinforce the importance of antihypertensive therapy and screen for adherence barriers.
- Addressing patient beliefs and forgetfulness can improve medication adherence in AAD survivors.

461
Aortic regurgitation (AR) is when the aortic valve does not close or seal properly, leading to backward blood circulation from the aorta into the left ventricle during diastole. Common causes of AR include rheumatic heart disease, congenital valve defects, and aortic root dilation. Managing AR requires a multifaceted approach to alleviate symptoms, preserve left ventricular function, and address the underlying cause of the regurgitation. Patients with symptomatic AR or significant left...

Inhaled medications are crucial for managing chronic obstructive pulmonary disease (COPD) and asthma. They are essential for effective treatment and control, ensuring optimal respiratory health and well-being. Inhaled medication delivers drugs directly to the lungs, providing a rapid onset of action and reducing systemic side effects compared to oral or injectable medications. Three primary types of inhalation devices are used to administer these medications: nebulizers, metered-dose inhalers...

A fixed action pattern (FAP) is a specific, hard-wired sequence of behaviors that occurs in response to an external stimulus, called a sign stimulus. The behavior is “fixed” because it is essentially unchangeable—proceeding similarly across individuals of a species every time it occurs.

01:15Aortic Regurgitation I: Introduction
683
IntroductionAortic regurgitation is characterized by the backward flow of blood from the aorta into the left ventricle during diastole and arises from the improper closure of the aortic valve. This condition results in left ventricular volume overload and can stem from both acute and chronic etiologies, each contributing uniquely to the disease's progression and symptomatology.Acute and Chronic CausesAcute aortic regurgitation often results from events that suddenly impair the integrity of the...
