omega-3 fatty acids and cardiovascular disease

the following comments are from jonathan berz on the blog on fish oils and cardiovascular disease, see http://gmodestmedblogs.blogspot.com/2016/09/omega-3-fatty-acids-and-cardiovascular.html . 
they did comment in the study that the observational data on fish did suggest a threshold effect, though the threshold was a little different for different clinical outcome associations.  Jonathan did send this out a few weeks ago, so sorry it’s taken so long after the original blog. geoff

Thanks for reviewing this Geoff. Two points I wanted to add
1.       Not all fish are create equal as you have alluded to. See slide below which shoes quite a variation ( the tilapia that is ever present is probably not so beneficial in this department, for example )

2.       Also to add is that there seems to be a threshold effect (in the healthy populations observational studies) as shown on the attached slide from a review by Mozaffarian (Dean at Tufts Nutrition )  from a talk I have given

air pollution and heart disease

Yet another study found an increase in heart disease in people exposed to air pollution/fine-particulate matter exposure (see  cad air pollution lancet2016  in  dropbox , or doi.org/10.1016/ S0140-6736(16)00378-0). details: --6795 participants. aged 45-84, enrolled in the Multi-Ethnic Study of Atherosclerosis and Air Pollution (MESA Air) from 6 different US cities (Baltimore, Chicago, LA County, New York City, St Paul, Winston-Salem) --median age 62, 53% women, 39% white, 12% Chinese, 27% black, 22% Hispanic), 50-80% with at least some post-high school education, 15% smokers, BMI 28, 45% with hypertension and SBP 128 mmHg, 12% diabetic, 15% on statins and cholesterol/HDL/LDL=190/50/115 --followed 10 years with repeated measurements of coronary artery calcium by CT (CAC score) as well as carotid artery intima-media thickness (CIMT); concentrations of fine particulate matter (PM 2.5 , which refle...

UPDATE: ASCVD risk factor critique

I decided to do an extensive update of my prior ASCVD (atherosclerotic cardiovascular disease) risk analysis and critique of risk calculators, with much more information about the “non-traditional” risk factors. I felt that there should be more data/clarification, since I think we are really undertreating/not preventing the most common cause of death by relying on the current ASCVD risk calculators   -- Cardiovascular risk models:      -- many of us rely on the various cardiovascular risk models to determine the appropriate approach to patients, and these are often integrated into the electronic medical records      -- these risk models have several very important limitations:          -- they are typically based on community data, eg from the Framingham study etc. But, in clinical practice, we are dealing with the individual and not the community:          ...

Very low LDL levels: benefit without harm

​ A recent meta-analysis of lipid-lowering shows that remarkably low levels of LDL cholesterol provide clinical cardiovascular benefit with no clear  increased harm  (see  lipids very low LDL benefit JAMAcardiol2018  in dropbox, or doi:10.1001/jamacardio.2018.2258). Details: -- 4 trials were looked at:     -- the Cholesterol Treatment Trialists Collaboration (CTTC), a meta-analysis of several RCTs that compared different LDLs achieved through statins, median follow-up of 4.9 years, 1922 vascular events     -- 3 RCTs evaluated non-statin LDL lowering therapies:         -- IMPROVE-IT study with ezetimibe (n= 18,144), median follow-up 6.0 years, 5104 vascular events         -- FOURIER study with the PCSK9 inhibitor evolocumab (n=2,034), median follow-up 2.1 years, 184 vascular events         -- RE...
