OBJECTIVE:

To compare the blood concentration of Troponin I (TI) in pregnant patients without and with severe preeclampsia (SP).

MATERIALS AND METHODS:

Prospective, cross-sectional study, conducted in patients of a medical unit of high specialty of gynecology and obstetrics of Mexico City admitted in the period from January to May of the year 2019. Patients of any age and parity with pregnancy > 20 weeks were selected. Those with previous diseases that may condition myocardial damage were excluded. Venous blood was taken to quantify TI using the “Triage Cardiac Panel”® device of the Biosite® brand that runs an indirect immunofluorescence program coupled to a reader called “Triage Meter”®. For this test the normal value of TI is 0 to 0.4 ng/mL. An electrocardiogram and a chest X-ray were also performed. The results of both groups were compared. Descriptive statistics and the paired Student's T test were used.

RESULTS:

71 women met the selection criteria. Two groups were formed: 37 patients without preeclampsia (group A) and 34 women with PS (group B). The blood concentration of TI in group A was 0.05 ± 0.008 ng / ml and in group B 0.05 ± 0.02 ng/mL (p = 0.30). In group B electrocardiographic abnormalities were found in 14.70% (5 cases) whose TI values were normal. Chest x-ray was normal in 100%.

CONCLUSIONS:

the blood concentration of TI in pregnant patients without and with PS was normal, including 5 preeclamptic women with electrocardiographic abnormalities.
