Breaking Down the Cost of Direct Primary Care
Direct Primary Care (DPC) is gaining popularity as an alternative healthcare model that offers patients more personalized and accessible care.

Understanding the cost of direct primary care is essential for anyone considering this healthcare option. This article breaks down the expenses involved, what you get for your money, and how it compares to c

The patient-media twelve- The white coats patients quote between visits — and why ApoB is bad for their business
I used to search for physicians online who would tell me I could ignore LDL. I have the physique. I am insulin sensitive. Triglycerides look great. I wanted the fantasy to be true. It was a good hypothesis. It has failed in front of me. Patients now walk in already subscribed. They are quoting a short list of doctors, a Harvard-Oxford YouTube channel, an engineer, and a fasting cardiologist with a million subscribers. Below is that list, what they actually sell, and the step

How I Went From Lipid Denialist to Lipid-Lowering Advocate- How Conservatives are More at Risk of Coronary Artery Disease Now More Than Ever Thanks to Alternative Social Media
By Stefan Hartmann, PA-C My questioning of lipids began in PA school in 2016, when a physician gave our class a lecture on evidence-based medicine. He showed us mortality data on statins. When you look at mortality alone, the number needed to treat can look underwhelming. He also explained relative risk reduction in a way that made it feel, to me at the time, like a Big Pharma manipulation of data. That lecture planted a seed. I adopted the paradigm that LDL elevation was ove

I measured 1,000 lipid NMR and 1,000 apo B and now just order apo B
I used to put substantial weight on LDL subfractions. The theory was compelling: small, dense LDL particles were believed to be more dangerous than large, buoyant LDL particles because they may circulate longer, penetrate the arterial wall more readily, bind less effectively to the LDL receptor, and be more susceptible to oxidative modification. Early observational studies supported this idea. Studies such as the Québec Cardiovascular Study, prospective studies of myocardial

Social Media Told This Patient to Buy Every Longevity Supplement- Clinical Context Was missing
Every week I meet patients who come into my office with a list of peptides, supplements, hormones, and biohacking products they found online. They're intelligent people. They listen to Huberman. They follow Brian Johnson. They watch podcasts. They read Reddit. They aren't looking for shortcuts—they're trying to optimize their health. But they often make one fundamental mistake. They start with the treatment instead of the diagnosis. Recently I had a great conversation with on

No, the yellow material in that carotid artery is not CRP. It is atherosclerotic plaque, specifically the lipid-rich necrotic core and atheroma that has built up inside the carotid artery.
During a carotid endarterectomy, the surgeon opens the carotid artery and removes the plaque that is narrowing the vessel. What is in that yellow plaque? Mainly: 1. Cholesterol-containing lipids Cholesterol esters Free cholesterol Oxidized lipids These lipids largely arrive because ApoB-containing particles (LDL, VLDL remnants, Lp(a), etc.) entered the artery wall and became trapped. ApoB is basically the "delivery vehicle" — every ApoB particle carries one atherogenic partic

What about hs-CRP? Isn't that important for CAD? Eh...
Well... first measure it a couple times because you may have just had a little cold illness when you measured hs-CRP at jacked it up. Then... Consider logically that hs-CRP can’t mechanically itself cause an occlusion. The data suggest that hs-CRP is capturing a different component of cardiovascular risk than ApoB. It is not simply another measure of cholesterol exposure. It appears to reflect the inflammatory environment that makes vascular disease more likely and plaques m
