Case: Rising Coronary Artery Calcium in a Patient Who Has a Normal Stress Echo with an Abnormal ECG

Ethan J Weiss, M.D.

A 74-year-old physically active man exercises daily, takes a statin for hyperlipidemia, and has no other risk factors aside from a mildly elevated hemoglobin A1c. His most recent lipid profile, in January 2015, was: Total-c: 144 mg/dL LDL-c: 84 mg/dL HDL-c: 48 mg/dL Triglycerides: 59 mg/dL His coronary artery calcium scores were 109.5 in the year […]

Cardiovascular Risk Prediction: Two More Studies, Little Progress

Larry Husten, PHD

Two studies published in JAMA provide new data — and, perhaps, some additional clarity — about using additional markers to help improve risk prediction for coronary heart disease (CHD) and cardiovascular disease (CVD). In one study, Joseph Yeboah and colleagues used data from 1330 intermediate-risk participants in the Multi-Ethnic Study of Atherosclerosis (MESA)  to analyze the prognostic value […]

CardioExchange Editors, Staff

Drs. Paul Ridker and Sanjay Kaul offer their perspectives on a new coronary artery calcium/C-reactive protein study, published in the Lancet, and three of the study authors respond.

Is Coronary Calcium Better Than CRP for Predicting CV Events?

Larry Husten, PHD

A new study suggests that people with low LDL levels and high CRP levels may benefit from coronary artery calcium (CAC) scans to identify those who are most likely to benefit from statin therapy. In a paper published in the Lancet, Michael Blaha and colleagues analyzed data from 950 people enrolled in the Multi-Ethnic Study […]
