Association between the increased level of high-sensitive CRP (hs CRP) and non-arrhythmic ECG changes and echocardiographic abnormalities in patients with acute coronary syndrome.

BACKGROUND: Abnormality in the cardiovascular system such as left ventricular dysfunction caused increased serum CRP and change in electrocardiography pattern. The present study aimed to understand the association between increased levels of highly sensitive CRP (hs-CRP) and non-arrhythmic ECG changes and electrocardiographic abnormalities in patients with the acute coronary syndrome.

METHODS: This study was done on 120 patients diagnosed with acute coronary syndrome and hospitalized at CCU. The patients were classified into two groups, one group with an increased level of hs-CRP and another with a normal hs-CRP level.

RESULTS: The patients with an increased level of hs-CRP showed a significantly higher level of cardiac enzymes also ST-segment elevation myocardial infarction (STEMI) was seen in the group with an increased level of hs-CRP than those with normal serum hs-CRP level, but another diagnosis including unstable angina, non-STEMI, heart failure, and emergency hypertension was similarly observed in both groups. Two groups were assessed in terms of left ventricular ejection fraction (LVEF), left ventricular end-diastolic diameter (LVeDD) the prevalence of valvular heart disease, and wall motion abnormality, also showed that groups with increased hs-CRP level, ST-segment elevation leads more significant differences than a normal group (P=0.001).

CONCLUSION: Patients with an increased level of hs-CRP can be diagnosed as STEMI but not valuable to suppose as echocardiographic abnormalities such as left ventricular dysfunction or hypertrophy.
