The Correlation Between Kidney Function Tests and Complete Blood Count in Iraqi Patients with Chronic Hypertension

Hypertension, also known as the silent killer, is a condition that typically remains asymptomatic until it causes significant harm to the cardiovascular system. Unmanaged hypertension can lead to renal failure, myocardial infarction, and even mortality. Kidney and blood pressure (BP) have a significant correlation with renal failure, particularly renal disease, leads to an increase in blood pressure. On the other hand, high blood pressure worsens the decrease in kidney function in those with kidney disease. This study aims to examine the correlation between kidney function tests (KFTs) and complete blood count (CBC) in Iraqi patients with chronic hypertension. The average disparity in kidney function tests (KFTs) between individuals with chronic hypertension and the control group. Urea, creatinine, and uric acid showed statistically significant increases (p<0.01). The findings indicated a noteworthy reduction (p<0.01) in HGB, HCT, MCH, and MCV concentrations among individuals with chronic hypertension. There is a strong and statistically significant association (p<0.01) between the average increase in urea and creatinine levels and the average reduction in MCH and MCV levels. Additionally, a significant correlation (p<0.01) exists between the uric acid level and deficiencies in HGB, HCT, MCH, and MCV. However, no statistically significant connection (p>0.01) was seen between HGB and HCT levels and urea and creatinine levels. Conclusions: Hypertension individuals with low levels of HGB, HCT, MCH, and MCV tend to have elevated levels of urea, creatinine, and uric acid. Thus, anemia may be advised for people suffering from hypertension and renal illness.
