New Skeptical Cardiologist Content is on Substack

It's been a while since I've posted here on my WordPress Blog. I'm still monitoring this website and answering comments but new if you are interested in new content head on over to Substack. It's clear to me that Google searches for subjects that I've written on will easily find my content here but not necessarily on Substack so if you have landed here via a Google search and want new content from the Skeptical Cardiologist, you should sign up for my Substack newsletter....

Since 2022, the skeptical cardiologist has been publishing articles both here, at WordPress, which is my original OG blog website and at Substack. Substack is an online publishing platform and software service that allows writers, journalists, and other creators to publish newsletters, podcasts, and video content and monetize it through paid subscriptions, bypassing traditional media gatekeepers. There are currently 25 million active users....

Flu season is just around the corner, which means it is time for you to ponder whether to get a flu shot. The skeptical cardiologist may have been on the fence about getting another COVID-19 booster vaccine at times, but he has always gotten the recommended annual flu vaccine, even when his employer didn’t mandate it. Influenza, of course, is a huge killer that causes around 36,000 deaths per year in the United States....

Individuals who have engaged in an active and exemplary lifestyle free of any symptoms lifelong can still be at extremely high risk for heart attack and sudden death. In June of 2024 I saw in my Encinitas cardiology office a seventy-year-old man (we’ll call Bernard) who grew up a block from the beach, started surfing at age 12 years, and was still surfing five times a week at a very high level....

Thoughts on a study that shows those who play racquet sports live 10 years longer than those who do no activity.

I had a lot of good comments on my recent pickleball post but one in particular seized my attention. I recently subscribed to the youtube channel of Cara Beth Lee (CBLeeMD), an orthopedic surgeon i…

I will be visiting a dentist in Encinitas next week and as I am sitting in the dentist's chair many skeptical thoughts will enter my consciousness

In 2016 the skeptical cardiologist wrote a two-part series that expressed doubts about the value of routine dental visits. A few days ago I shared those articles with a physician friend who had exp…

In 2019 the skeptical cardiologist wrote about a trial that he thought was practice changing. a study published in European Heart Journal in October has demonstrated that routine ingestion of BP meds at bedtime as opposed to waking results in improved 24 hour BP control with enhanced decrease in asleep BP and increased sleep-time relative BP decline (known as BP dipping.)...

The skeptical cardiologist has become an unbridled pickleballl enthusiast in the last year. Since my teens, I’ve had a fondness for all activities that involve whacking a moving ball with a racquet-type instrument, ranging from ping-pong to badminton to racquetball. Tennis was my focus for 40 or so years until a persistent pesky tennis elbow and knee pain convinced me to hang up my racquet…...

When my dad was 70 he suffered a small heart attack, aka MI, and one of my partners performed an invasive coronary angiogram on him which demonstrated a long, complicated, severe blockage in his right coronary artery. The other two coronary arteries had significant blockages as well and my partner recommended that he undergo coronary artery bypass surgery (aka CABG, pronounced cabbage)....

In a previous post, the skeptical cardiologist enthusiastically proclaimed CCTA as the ideal tool for assessing stable individuals for the presence, characteristics, and severity of atherosclerotic plaque (aka the atherosclerotic burden) in the coronary arteries. That CCTA-derived coronary artery disease (CAD) burden is the best clinical tool we have for determining the short and long-term risk of heart attack and stroke, the major manifestations of atherosclerotic cardiovascular disease (ASCVD)....

The skeptical cardiologist wrote a long post in 2017 entitled "Do Statins Cause Memory Loss? The Science, The Media, The Statin-Denialist Cult, and The Nocebo Effect" which was updated in 2019. If you'd rather not be bothered with the longish discussion in that post, complete with scientific references, the answer is no, statins don't cause memory loss. The FDA added a warning to the statin patient information in 2012 based on a few case reports....

This is a quick post to notify individuals with high lipoprotein(a) levels of a clinical trial of lepodisiran that they may qualify for. I’ve written in detail about the hidden risk of lipoprotein(a), (aka Lp(a)), here and here. If you or family members have developed atherosclerotic complications at an early disease you need to be tested for it. Briefly, Lp(a) is the strongest single inherited (monogenetic) risk factor for the early development of coronary artery disease, heart attacks and strokes....
