Correlation between Serum Calcium Level with Blood Pressure Level In Patients Presenting With Type 2 Diabetes Mellitus

Abstract

Objective: To study the relationship between serum calcium level and blood pressure level in
patients presenting with type 2 diabetes mellitus.
Methods: This cross sectional study was conducted at East Medical Ward, Department of
Medicine Mayo Hospital Lahore. This study was done in six months period from March 10, 2015-
Sep 10, 2015. The non-probability consecutive sampling technique was used in this study.
Informed consent and demographic information like name, age and address was recorded.
Systolic and Diastolic Blood pressure was measured by using standard and absolute
sphygmomanometer. 3ml Blood sample of each patient was taken with informed consent and
was sent to the laboratory of the hospital to assess serum calcium level (as per operational
definition). Reports were assessed and calcium level was recorded. Pearson correlation
coefficient was calculated to measure the relationship between serum calcium level and systolic
& diastolic blood pressure. pvalue ≤0.05 was considered statistically significant.
Results: In our study the mean age of the patients was 59.42±11.02 years, 30% patients were
males and 70% patients were females. The mean SBP value of the patients was 140.56±11.35
mmHg and mean DBP value was 87.98±6.11 mmHg. In this study the mean value of calcium level
of the patients was 8.22±1.24 mg/dl. The negative correlation was observed in our study between
the calcium level and SBP, DBP of the DM patients i.e. r= -0.665 & -0.401 respectively
Conclusion: The study concluded that negative correlation was observed between the serum
calcium level and the blood pressure level in patients presenting with type 2 diabetes mellitus.
