Butter Beware? Do Omega-3 Fatty Acids in Margarine Cut Heart Attack Risk?

Margarine fortified with Omega-3 fatty acids may not reduce heart attack risk in patients who have previously experienced a heart attack, according to researchers in the Netherlands who published their findings in the Aug. 29, 2010, issue of The New England Journal of Medicine.
Omega 3 fatty acids are considered essential for human health but they cannot be made by the body – they can only be obtained through such foods as fish, some plants and nut oils. In recent years, many makers of margarine have added Omega-3 oils to their spreads, citing their potential heart-healthy benefits.
But according to the Netherlands Heart Foundation, Omega 3 oils did not “significantly reduce the rate of major cardiovascular events among patients who had had a myocardial infarction.” A myocardial infarction is most commonly called a heart attack. A link to the published study online can be found here.
The study involved nearly 5,000 men and women, ages 60 to 80, who were being treated for heart disease with medications ranging from antihypertension drugs to cholesterol-reducing statins. Participants consumed about four teaspoons of Omega-3 enriched margarine each day over a three-year period. Those who ate the Omega-3 enriched oils did not experience any fewer heart events than those in a placebo group who ate plain margarine.
The study’s researchers pointed out that the participants were already well-treated for their heart conditions, which may have reduced the potential positive benefit of consuming Omega-3 oils.
Question for comment: How will this study potentially affect your future margarine and/or butter purchases? Or do you have another comment?

On Monday, April 17, 2000, I participated in one of the most strenuous cardio workouts I’d ever been through in my life. In hindsight, it probably saved my life. During the workout, my calves severely cramped and as I massaged them out, my left hand did the same. Eventually, my calves loosened up but the tip of my left index finger became cold and numb.
I went to Hennepin County ER Tuesday morning with my index finger symptom and was sent home with the diagnosis of Raynaud’s Syndrome. The discomfort in my finger continued into Thursday and after reading up on Raynaud’s, I knew that wasn’t my issue. I was able to get in to see an internist and he listened to my entire story and began examining my legs; he found no visible pulse. After taking what he needed to run a few tests, the internist sent me to Dr. Alden, a vascular surgeon, for a follow-up opinion.
Dr. Alden was stumped as well since he could not find a pulse in my feet with a Doppler Ultrasound. He registered me for a major ultrasound work-up the next day at Abbott Northwestern Hospital. So on Friday, April 21st, I went to the hospital for my work-up. Dr. Alden met me there, stating his fears that I was having blood clots and his desire to have me check in once the ultrasound was done. It was Good Friday.
Saturday, the angiogram revealed blood clots in my legs and my left arm. The echocardiogram on Monday revealed that I’d had a heart attack as images showed a blood clot and an aneurysm on my left ventricle. Another angiogram on Wednesday revealed a dissection of my left anterior descending artery (LAD) and most likely the cause of the clot and aneurysm.
On May 1, 2000, Dr. Frazier Eales performed bypass surgery on my LAD using a mammary artery in my chest. Additionally, Dr. Eales removed the blood clot and as much of the aneurysm as possible without having to restructure my left ventricle.
Oh yeah, did I mention I was 28 years old when this occurred?
That was just over 10 years ago. It hasn’t all been easy. Beyond the physical healing there is a mental aspect that must be taken into consideration. While my body was healing physically, my mind was still pretty sharp and confident. Once my physical healing began its final stages, I broke down mentally and emotionally. This is when the real healing began. Unfortunately, the doctors can’t prepare you for this stage. At 28 years old, and probably at any age, I don’t know that any doctor can prepare someone for the feelings of vulnerability and fragility that follow such an event and the depression that follows. Truth be told, I’m a competitive s.o.b. and I decided I wasn’t going to let this get the better of me. That attitude combined with counseling brought me through the dark times.
But, I’ll always carry the physical and emotional scars with me. When it happens at such a young age, I don’t know if you ever get over it. What I do know is that I came away with a real appreciation of just how precious and fragile life truly is. Believe me, it is something to be cherished. The path wasn’t always easy, but going down it truly changed my life for the better.

Four or five days prior to my 80th birthday, I noticed chest pain from walking more than five or six steps. One of my daughters was here to celebrate my birthday with me and we would go walking. I noted pain on walking too fast. The day of my birthday in November of 2008, I woke at 3 a.m. with chest pain without exertion. This was a new symptom, although it felt similar to that when walking.
As I debated about my course of action, I remembered my brother’s incident with rather atypical symptoms sych as stomach discomfort that wasn’t relieved by antacids. He had waited 24 hours before consulting a physicians and then had to be air-lifted by helicopter from his small town hospital to a major hospital in the Twin Cities- Abbott Northwestern. He ended up having a quintuple bypass surgery.
As to my own symptoms, I depated a few minutes, then called my daughter (who also happens to be a nurse) and asked her to take me to the hospital. It turns out, I had a 98% blockage in my anterior descending coronary artery and needed a stent. The procedure was performed within an hour of my arriving in the ER, and I was sent home the next day so I could enjoy birthday pizza, cake and ice cream with my family.
The moral of my story is that when in doubt, get medical help immediately, don’t delay!
