Cultural competence: cardiovascular medications

Area of Science:

• Pharmacogenetics
• Cardiovascular Pharmacology
• Nursing Assessment

Background:

• Interethnic and racial variations exist in drug-metabolizing enzymes due to enzyme polymorphisms.
• Antihypertensives are the most studied cardiovascular drugs in pharmacogenetics.
• Limited data exists on ethnic differences in the effectiveness of cardiovascular drugs beyond antihypertensives.

Purpose of the Study:

• To highlight the association between enzyme polymorphisms and drug response in diverse populations.
• To emphasize the need for culturally sensitive nursing assessments regarding drug metabolism.
• To provide guidance for nurses on assessing culturally important factors influencing pharmacogenetics.

Main Methods:

• Review of existing pharmacogenetic studies on cardiovascular drugs, particularly antihypertensives.
• Analysis of ethnic and racial differences in drug metabolism and treatment response.
• Identification of gaps in knowledge regarding ethnic variations in drug effectiveness.

Main Results:

• A consensus exists for antihypertensive treatment in Black patients, but not for other cultural groups.
• Enzyme polymorphisms significantly impact drug metabolism and response.
• Nurses need to consider a patient's ethnic background for potential risks in drug metabolism.

Conclusions:

• Enzyme polymorphisms are critical in understanding interethnic differences in cardiovascular drug efficacy.
• Culturally informed nursing assessments are essential for optimizing antihypertensive therapy.
• Further research is needed to establish clear treatment guidelines for diverse ethnic populations receiving cardiovascular drugs.
