CARPREG II fine-tunes assessment of cardiac complication risk in pregnancy

View on the News

Detailed patient evaluation still required

This update and expansion of the original CARPREG scoring system is a “useful starting point” for prediction of the risk of pregnancy in women with cardiac disease, according to Uri Elkayam, MD.

However, a detailed and lesion specific evaluation is still required for a more precise determination of risk for any given patient, Dr. Elkayam cautioned in an editorial accompanying the article.

Clinicians need to thoroughly understand how the patient’s cardiac condition could be affected by hemodynamic changes during pregnancy, labor, delivery, and the postpartum period, Dr. Elkayam added in his comments.

To fully take advantage of CARPREG II, clinicians need to take into account the limitations of the scoring system, he said, including the fact that it is based on population studies.

“Although the system presented is designed to examine all adverse cardiac events that could have an impact on maternal health, it is less effective for distinguishing between mild and easily manageable events that do not have serious effects on maternal or fetal outcomes and those that may be severe, life-threatening, or require hospitalizations or early delivery,” he wrote.

Dr. Elkayam is with the department of medicine, division of cardiovascular medicine, and the department of obstetrics and gynecology, University of Southern California, Los Angeles. These comments are derived from his editorial in the Journal of the American College of Cardiology . Dr. Elkayam reported he had no relationships relevant to the contents of this paper to disclose.

Looking at patient data before or after 2001, investigators found the rates of most complications were consistent over time. However, rates of pulmonary edema decreased in the post-2001 period.

Multivariate analysis of these findings revealed 10 predictors of adverse cardiac events. Those included five general factors, including previous cardiac events or arrhythmia, four lesion-specific variables including pulmonary hypertension and coronary artery disease, and one process of care variable: late pregnancy assessment.

Only 4 of those 10 factors were included in the original CARPREG index, investigators noted.

In CARPREG II, each of the 10 factors is weighted with 1-3 points, depending on risk. For example, history of prior cardiac events was associated with a higher odds ratio, and so was assigned 3 points.
