Sex Differences in Coronary Artery Calcium and Mortality From Coronary Heart Disease, Cardiovascular Disease, and All Causes in Adults With Diabetes: The Coronary Calcium Consortium
RESULTS Among 4,503 adults with diabetes (32.5% women) aged 21–93 years, 61.2% of women and 80.4% of men had CAC >0. Total, CVD, and CHD mortality rates were directly related to CAC; women had higher total and CVD death rates than men when CAC >100. Age- and risk factor–adjusted hazard ratios (HRs) per log unit CAC were higher among women versus men for total mortality (1.28 vs. 1.18) (interaction P = 0.01) and CVD mortality (1.47 vs. 1.27) (interaction P = 0.04) but were similar for CHD mortality (1.48 and 1.48). For CVD mortality, HRs with CAC scores of 101–400 and >400 were 3.67 and 6.27, respectively, for women and 1.63 and 3.48, respectively, for men (interaction P = 0.04). For total mortality, HRs were 2.56 and 4.05 for women, respectively, and 1.88 and 2.66 for men, respectively (interaction P = 0.01).
CONCLUSIONS CAC predicts CHD, CVD, and all-cause mortality in patients with diabetes; however, greater CAC predicts CVD and total mortality more strongly in women.Sex Differences in Coronary Artery Calcium and Mortality From Coronary Heart Disease, Cardiovascular Disease, and All Causes in Adults With Diabetes: The Coronary Calcium Consortium — Diabetes Care 2020 Oct; 43(10): 2597-2606. https://doi.org/10.2337/dc20-0166
CVCT CardioBrief published online earlier this week a letter from a group of “clinicians, researchers and imaging specialists” who are concerned about the “presentation, interpretation and media coverage of the role of cardiac magnetic resonance imaging in the management of asymptomatic patients recovered from COVID-19.” It’s short and sweet but makes many excellent points. Let’s…Cardiac Testing Post COVID-19: Of Echos and MRIs — The Skeptical Cardiologist
Excellent post. Thanks for sharing your expertise Dr. Pearson.
I mentioned in my post entitled “Should You Utilize A Home Pulse Oximeter During COVID-19?” that I had purchased a home pulse oximeter and had used it to monitor my oxygen saturation (SpO2) levels during the time I had COVIDesque symptoms recently. Personally, I felt the device was returning accurate information and was helpful in…How Accurate Are Pulse Oximeters Labeled Not For Medical Use? — The Skeptical Cardiologist
And if you decide not to read Dr. Pearson’s entire article here’s your take home message:
During my illness I would measure my SpO2 twice daily and at times when I felt short of breath. When I felt the worst I noted the SpO2 had dropped to 95%. Within 24 hours it rebounded and I recorded >96% thereafter.
If the SpO2 had progressively dropped and consistently showed values <90% I would have contacted my primary care physician and described the constellation of signs (pulse rate, respiratory rate, BP, and SpO2) and symptoms (shortness of breath, cough, headache, fatigue, etc.) that I had and seek his advice on what to dohttps://theskepticalcardiologist.com/2020/09/12/how-accurate-are-pulse-oximeters-labeled-not-for-medical-use/
I encourage all to read the entire article, links provided above.
Thanks for the research Dr. Pearson.
A study published yesterday in JAMA has the skeptical cardiologist very concerned about the long-term cardiac effects of COVID-19 infection. The investigators performed cardiac MRI (CMR) on 100 patients with documented COVID-19. Cardiac MRI is now considered the gold-standard for noninvasively measuring pathologic changes in cardiac muscle. In this study of a cohort of German…

Thank you Dr. Pearson.
And the following is a link to the Medscape article:
A finding of any type of polyp in the colon increases the risk for colorectal cancer (CRC), according to new findings from a large Swedish study.
At 10 years, the cumulative colorectal cancer incidence was 1.6% among patients with hyperplastic polyps, 2.5% among those with sessile serrated polyps, 2.7% for tubular adenomas, 5.1% for tubulovillous adenomas, and 8.6% for villous adenomas, as compared with 2.1% for the control group.
However, a higher risk for colorectal-related death was only observed in patients with sessile serrated polyps, tubulovillous adenomas, or villous adenomas.
The study was published online March 16 in Lancet Gastroenterology & Hepatology.
Boldface sections are mine.
I had my first virtual visit with my physician yesterday. I mentioned that I was postponing my colonoscopy this year for pandemic reasons. She said that’s fine, don’t worry about it. I read this article today. Now I know why I’m on a three year callback.
For far too long, many patients have undergone a cardiac test that carries grave risks with the misunderstanding that they are getting the definitive assessment of their coronary arteries. Chances are if you have visited an emergency room in the USA with chest pain and you weren’t clearly having an acute heart attack, you ended up…
Thank you Dr. Pearson.
We’ll never see a case like this in our line of work but it’s still a lot of fun to read on a Saturday morning while recuperating from a business trip.
The skeptical cardiologist has been evaluating a demo version of AliveCor’s new KardiaMobile 6L. I have been a huge advocate of Kardia’s single lead ECG and use it with great success in dozens of my afib patients. I’ve written about how this personal ECG monitoring empowers patients and providers and is a crucial component of…
Thanks Doctor for the ECG history lesson and for sharing your insights.
And congratulations on the Stanley Cup!
