Association Between Resting Heart Rate And Coronary Artery Disease, Stroke, Sudden Death And Noncardiovascular Diseases: A Meta-Analysis

Group Presentation

Literature Review

Key Points for PowerPoint:

· Heart rate reflects the balance on sympathetic and parasympathetic activity.

· High natural resting heart rate is associated with risk factors.

· Importance of resting heart rate has been recognized.

· High Resting heart rate is a sign of over activity which is associated with an increased risk of sudden death

Heart rate reflects the balance on sympathetic and parasympathetic activity. High natural resting heart rate is associated with traditional risk factors for cardiovascular diseases, levels of inflammatory markers, and functional decline. A high rate can be a marker of sympathetic overactivity, which is associated with an increased risk of sudden death that usually results from ventricular fibrillation. Sympathetic overactivity may increase risk of obesity that could induce insulin resistance. A high resting heart rate could increase stress which can increase mechanical load, tensile stress, blood pressure, and cardiac work.

Research Method

Key points for PowerPoint:

· Meta-analysis method. Virtual library through MRU home page. Researcher accessed EBSCOhost and selected both Medline and CINAHL. Following keywords were entered “Heart rate”, “Coronary artery disease”, and “Non-cardiovascular”. Search was limited to full text, peer reviews, and abstract available. Published within the last five years.

For this study, a meta-analysis method was used to synthesize different results found among several studies. The researcher accessed the virtual library through the MRU home page. Then, the researcher accessed the EBSCOhost databases. Once there, the researcher selected both MEDLINE Complete and CINAHL Complete. An advanced search was performed, for which the following keywords were entered in the Boolean search: “Heart rate”, “Coronary artery disease”, and “non-cardiovascular” The search was limited to references providing full text, peer reviewed, and abstract available. A limitation was set for research published within the last five years, from March 2016 to March 2021. Additionally, researcher consulted only articles published in English and Spanish. The search provided access to a total of 4 articles, of which only seven (1) studies were selected based on their relevance with the topic; the other 3 were discarded.
