Heart Attack – What Is LDL/HDL Ratio?

The LDL/HDL ratio is a better indicator of the risk of having a heart attack than the total cholesterol level. What is the LDL/HDL ratio?

High density lipoprotein (or HDL for short) is also known as "good cholesterol." It picks up extra cholesterol in the blood and returns it to the liver. Low density lipoprotein (or LDL) is also known as "bad cholesterol". It is the main transporter of cholesterol in the body. But too much LDL over many years can result in atherosclerosis (the narrowing and hardening of arteries) and lead to heart disease or a heart attack.
The HDL/LDL ratio looks at the ratio of good cholesterol (HDL) to bad cholesterol (LDL). The ratio is determined by dividing the LDL cholesterol into the HDL cholesterol. For example, if a person has an HDL cholesterol of 50 mg/dL and an LDL cholesterol of 150 mg/dL, the HDL/LDL ratio would be 0.33. The goal is to keep the HDL/LDL ratio above 0.3, with the ideal HDL/LDL ratio being above 0.4.

My husband suffered a heart attack in January 2008. He is doing well and is under the care of an excellent cardiologist. According to his last blood test, his LDL/HDL ratio is normal, but his level of HDL is very low.

Heart Attack – What Are Triglycerides?

From the American Heart Association website:

Triglycerides are the chemical form in which most fat exists in food as well as in the body. They’re also present in blood plasma and, in association with cholesterol, form the plasma lipids.

Triglycerides in plasma are derived from fats eaten in foods or made in the body from other energy sources like carbohydrates. Calories ingested in a meal and not used immediately by tissues are converted to triglycerides and transported to fat cells to be stored. Hormones regulate the release of triglycerides from fat tissue so they meet the body’s needs for energy between meals.

Heart Attack – Olive Oil

Olive oil is good for heart health. My husband has been told this several times by a variety of health care professionals since his heart attack on January 8, 2008. But why is olive oil so good for the heart?

Virgin olive oil is made from the first pressing of olives and contains higher levels of a class of antioxidants known as polyphenols than more refined olive oils that come from later pressings.

Researchers say these polyphenols may provide another way to reduce the risk of heart disease in addition to the heart-healthy benefits attributed to the monounsaturated fatty acids found in olive oil.

Recent studies have suggested that the bulk of olive oil’s heart-healthy benefits comes from good fatty acids (monounsaturated fatty acids), but researchers say polyphenols may also contribute to those benefits and further reduce the risk of heart disease.

Heart Attack – Almonds

In addition to eating olive oil each day, my husband’s cardiologist recommends eating almonds to reduce the risk of a heart attack. What is it about almonds that helps keep our hearts healthy?

Almonds contain significant stores of antioxidants (35% of the daily recommended value for vitamin E), as well as fiber, arginine—a protein that keeps arteries elastic—and phytochemicals known as plant sterols, which help lower harmful LDL cholesterol levels while maintaining beneficial HDL levels. A three-month study done at Loma Linda University and presented at the Experimental Biology 2000 conference found that when participants added just two ounces of almonds a day to their already low-saturated fat and cholesterol diet, their levels of harmful LDL cholesterol dropped even lower.

Heart Attack – Lipoprotein

Lipoprotein is a cholesterol particle. Elevated levels of lipoprotein in the blood results in an increased risk of heart attack, and the lipoprotein level is not associated with a person’s LDL level.

Lp(a) was first pinpointed in the blood some 40 years ago, but doctors don’t normally screen for this lipoprotein because no standardized screening exists and because even when the Lp(a) is known, very little can now be done to modify it. Unlike other kinds of cholesterol, Lp(a) in the blood is 95 percent determined by genes, so drugs and changes in diet have little effect on it, Danesh said.

Lp(a)’s exact role in the blood also is unknown, Scanu said, although researchers do know it’s a fat-carrying particle that includes a protein that mimics the body’s natural clot-busting properties.

Heart Attack – A1C Test

My husband suffered a heart attack at the age of 56 on January 8, 2008. He is doing well now, and is under the care of our excellent primary care and cardiac doctors. A few weeks ago, Jim reviewed the results of his blood tests with our primary care physician. She noted that his blood sugar level was 109, which is higher than the 100 target. She ordered a A1C test to check for pre-diabetes for Jim’s next round of blood tests. But what is the A1C test?

The A1c test is used primarily to monitor the glucose control of diabetics over time. The goal of those with diabetes is to keep their blood glucose levels as close to normal as possible. This helps to minimize the complications caused by chronically elevated glucose levels, such as progressive damage to body organs like the kidneys, eyes, cardiovascular system, and nerves. The A1c test gives a picture of the average amount of glucose in the blood over the last few months. It can help a patient and his doctor know if the measures they are taking to control the patient’s diabetes are successful or need to be adjusted.

Heart Attack: Study Shows How Diabetes Drives Atheroscerosis

This is a good post explaining how diabetes exacerbates atherosclerosis:

Not to hammer on the point too much, but excess body fat held over the years causes chronic inflammation, which enrages your immune system, which leads to atherosclerosis, which tends to kill you abruptly and without warning. All very avoidable. To make matters worse, excess fat – or rather all the food you ate in order to create the excess fat – creates a feedback mechanism that leads to insulin resistance and diabetes, and this makes the atherosclerosis-generation process run faster: "Experts once believed that atherosclerosis, or hardening of the arteries, developed when too much cholesterol clogged arteries with fatty deposits called plaques. When blood vessels became completely blocked, heart attacks and strokes occurred. Today most agree that the reaction of the body’s immune system to fatty build-up, more than the build-up itself, creates heart attack risk. Immune cells traveling with the blood mistake fatty deposits for intruders, akin to bacteria, home in on them, and attack. This causes inflammation that makes plaques more likely to swell, rupture and cut off blood flow. … In part because diabetes increases atherosclerosis-related inflammation, diabetic patients are twice as likely to have a heart attack or stroke. … Inflammation is blood vessels is one of the main drivers of atherosclerosis, and diabetes makes it much worse."

Heart Attack Recovery – Salt Intake Limits

Our primary care physician told us today that generally, my husband (a heart attack survivor), should not consume more than 2000 mg of sodium/day. Here’s a web page stating that 1 teaspoon of salt contains 2000 mg of sodium:

Sodium levels in salt. The American Heart Association (AHA) recommends that healthy adults reduce their sodium intake to no more than 2,400 milligrams per day. This is about 1 and 1/4 teaspoon of sodium chloride (salt).

They further recommend that if you have heart failure, you reduce your sodium to 2000 mg. Some doctors advise PAH patients to follow the AHA guidelines. Listings of the sodium content of various foods and other guidelines can be found on the AHA’s website (www.americanheart.org).

1/4 teaspoon salt = 500 mg sodium
1/2 teaspoon salt = 1,000 mg sodium
3/4 teaspoon salt = 1,500 mg sodium
1 teaspoon salt = 2,000 mg sodium
1 tsp baking soda = 1,000 mg sodium

The Cardiac-Diabetic Diet

Last week, my husband who is a cardiac patient, was told that he is pre-hyperglycemic (pre-diabetic). His glucose blood level is 109 and it should be below 99. So we must undergo another lifestyle/diet change. Jim has been following the cardiac diet. Now it looks like he’ll do better with the cardiac-diabetes diet. Here’s is the cardiac-diabetes diet that was given to us at the Boston Medical Center:

  • The Cardiac-Diabetic Diet is a special diet designed for patients with a history of both heart disease and diabetes. This eating plan is designed to help patients manage their cholesterol, blood pressure and blood sugar. Abiding by the principles of the cardiac-diabetic diet will help in preventing further complications of heart disease and diabetes:
  • What is a Cardiac-Diabetic Diet:
    -Low in total fat: limit oils, mayonnaise, salad dressing, margarine
    -Low in saturated fat: limit butter, lard, animal meat, coconut, cheese, ice cream
    -Low in trans fat: avoid packaged snack foods, chips, French fries, donuts
    -Low in sodium: avoid salt, pickles, ketchup, soy sauce, baking soda
    -Low in cholesterol: avoid whole milk, cream, egg yolk, organ meats
    -Low in concentrated sweets: avoid sugar, jelly, candy, syrup, marshmallow

You can still consume many of your favorite foods while following the cardiac-diabetic diet, but it is very important to pay attention to how much you are eating at each meal. Controlling portion sizes will help to limit your intake of fat, cholesterol, sodium and sugar. Following the Diabetic Food Guide Pyramid is an easy way to ensure you are eating a wide variety of food and getting all of the nutrients you need.
