Summary
Fatigue and stress impact blood pressure medication adherence. Black and White adults showed race and fatigue severity significantly predicted adherence, highlighting the need to consider racial differences.
Area of Science:
- Cardiovascular Health
- Psychology
- Health Disparities
Background:
- Medication adherence is crucial for managing hypertension post-myocardial infarction.
- Fatigue and stress are common but understudied factors influencing adherence.
- Racial disparities in cardiovascular disease outcomes persist.
Purpose of the Study:
- To investigate the relationship between fatigue, stress, and blood pressure (BP) medication adherence.
- To explore potential racial differences in these relationships among Black and White adults.
- To identify predictors of BP medication adherence in adults post-myocardial infarction.
Main Methods:
- Cross-sectional study of 152 Black and White adults with a history of myocardial infarction.
- Assessed fatigue, stress, and self-reported BP medication adherence.
- Used regression analysis to determine predictors of adherence.
Main Results:
- Over half (55%) reported moderate to severe fatigue.
- Fatigue and race significantly predicted BP medication adherence (p < .001), explaining 40% of variance.
- Black participants linked fatigue to distress (r=.40); White participants linked fatigue severity to adherence (r=.49).
Conclusions:
- Fatigue and race are significant predictors of blood pressure medication adherence.
- Racial differences exist in how fatigue impacts adherence and distress.
- Clinical evaluations of adherence should incorporate patient race and fatigue levels.

18
Angina, a symptom of myocardial ischemia, requires a structured nursing management approach to ensure effective care and prevent complications like myocardial infarction. Comprehensive nursing care involves assessing, diagnosing, planning, implementing interventions, and evaluating outcomes, all tailored to the individual patient's needs.Patient AssessmentNursing assessment begins with a detailed subjective evaluation of symptoms, which typically include chest pain or pressure radiating to the...

Effective preventive measures for coronary artery disease (CAD) focus on controlling modifiable risk factors, including cholesterol abnormalities and lifestyle changes.Cholesterol ManagementFirst, the Mediterranean diet and the American Heart Association advocate for maintaining low-density lipoprotein (LDL) cholesterol levels below 100 mg/dL, with a more stringent recommendation of below 70 mg/dL for individuals at high risk. LDL cholesterol, often termed "bad cholesterol," can lead to the...

IntroductionThe management of angina requires a comprehensive approach that includes pharmacological therapies, medical procedures, and lifestyle modifications.Pharmacological TherapiesAntiplatelet agents, such as aspirin, clopidogrel, prasugrel, and ticagrelor, play a pivotal role in preventing thrombus formation in patients with angina. These medications inhibit platelet aggregation and reduce the likelihood of myocardial infarction and other cardiovascular events.Anticoagulants, including...

Myocarditis is an inflammatory condition of the myocardium requiring meticulous nursing management for optimal patient outcomes. Effective management begins with a thorough assessment of the patient's medical history, paying close attention to past infections, autoimmune disorders, travel history, and exposure to toxins or drugs. Recent viral infections and systemic diseases are particularly relevant due to their potential role in triggering myocarditis.Physical Examination and MonitoringThe...
