Urine high sensitive Troponin I measuring in patients with hypertension

High sensitive troponin I (hsTnI) is one of the markers of cardiac damage. Its values increase two to three hours after a heart attack and remain elevated for days. Recent studies have shown that kidneys are the main organ of elimination of troponin from blood. Our previous studies have shown that troponin I is removed and concentrated in the first morning urine. Increased blood pressure is one of the most common comorbidities today. By measuring blood pressure, we can see the current value of the pressure, but we do not know what the values are during the rest of the day. The aim of our research was to determine if there is a difference in the concentration of troponin I in urine among patients suffering from hypertension and among healthy individuals. The study involved 20 participants divided into two groups. In the first group were healthy individuals, while in the second group were individuals with hypertension. The first morning urine was sampled and the hsTnI was measured using a highsensitivity test on the Immuno-enzymatic analyser Abbott Architect i1000SR. Within the normotensive group, the mean value of hsTnI in the first morning urine was 14.95 pg/mL, while in the group of participants with elevated blood pressure, the mean value of hsTnI in the first morning urine was 26.59 pg/mL. The difference between these two groups was statistically significant with p=0.0451 (p<0.05). By measuring hsTnI in urine and determining the difference between healthy and those with hypertension, a new diagnostic test for hypertension monitoring and detection would be obtained.
