Background: Epidemiological studies have reported the association between resting tachycardia (RT) and cardiovascular mortality, both in cardiac and non cardiac subjects.
Aims: To investigate the association between RT and clinically evident ischaemic heart disease (IHD) in diabetic patients.
Settings and Design: Retrospective analysis of the hospital data.
Data collection period - 2008-2009.
Material and Methods: Electro cardiogram recordings of diabetic patients (n=100) were used for the calculation of the resting heart rate (RHR). RHR > 90 beats/ minute (bpm) was considered as RT. Presence/ absence of IHD were noted from the patient case records. The association between RHR and the prevalence of IHD was analyzed by applying the x2 test by using the SPSS software 12 version. P values <0.05 were considered to be statistically significant
Results: Fifteen percent of the patients had RT and 28 % had clinical evidence suggestive of IHD. More than 50 % of those with RHR >90/bpm had IHD as compared to 23.5% in the group having RHR ≤90/bpm and the comparison between the two showed statistical significance (p=0.028).
Conclusions: This retrospective analysis reports a positive association between RT and the pre-existing IHD in diabetic patients. RHR could be considered as a clinical marker for clinically evident IHD. A careful search for coronary artery disease, including the administration of an angiogram need to be considered in all diabetic patients presenting with RT.
