Relationship Between Diabetes and Heart Disease

Diabetes is a disorder in which your blood glucose (sugar) levels are higher than normal. In Type 1 Diabetes, high blood glucose is because the pancreas produces little or no insulin for processing the glucose. In Type 2 Diabetes, the body is unable to use insulin well, thus causing high blood glucose levels. 

Type 2 Diabetes is the more common form of diabetes, amounting to about 90 to 95% of all diabetic diagnoses. It is related to the lifestyle of an individual and often occurs along with other lifestyle diseases.

Heart disease, also called cardiovascular disease or coronary disease, refers to various conditions of the heart, the most common being coronary artery disease (CAD), the narrowing or blockage of the blood vessels that supply blood to the heart. Other heart diseases include arrhythmia (irregular heartbeat), cardiomyopathy (disease of the heart muscle), and heart failure. Heart disease may lead to heart attacks and strokes. 

High blood glucose in diabetes can damage the blood vessels of your heart. Over time, this damage can lead to heart disease. Individuals with diabetes tend to develop heart disease at a younger age than those without diabetes. Further, adults with diabetes are at twice the risk of developing heart disease when compared to adults without diabetes.

Does Diabetes Cause Heart Disease?

In a diabetic individual, the body cannot use up all the glucose (sugar), so more of it sticks to the red blood cells and builds up in the blood. This build-up can block and damage blood vessels and the nerves that control them.

Diabetes worsens atherosclerosis, the most common cause of heart disease. Atherosclerosis is the buildup of cholesterol (plaque) in the blood vessels that supply oxygen and nutrition to the heart. The plaque can cause your arteries to narrow and block their blood flow.

When the cholesterol plaques break down, the body tries to repair the plaque rupture by sending platelets to seal it up. Because the artery is small, the platelets may block blood flow and prevent oxygen delivery to the heart. This results in the development of a heart attack.

This process can happen in all arteries of the body, resulting in a lack of blood supply to the brain and causing a stroke or a lack of blood supply to the feet, hands, or arms and causing peripheral arterial disease.

Individuals with diabetes are also more likely to have certain other risk factors for heart disease, such as high blood pressure or high cholesterol. Thus, people with diabetes are at higher risk for heart disease as well as heart failure, a condition in which the heart is unable to pump blood efficiently.

Symptoms of Heart Disease in Diabetes

The symptoms of heart disease depend upon the type of heart disease and may vary based on its severity. Some individuals may not even have any symptoms until they have a heart attack.

The most common symptoms of coronary artery disease in individuals with diabetes are:

• Pressure, tightness, or pain in the chest that may spread to your jaws, arms, neck, abdomen or back
• Shortness of breath
• Pain, numbness, weakness, or feeling cold in your legs or arms
• Fatigue
• Dizziness

Treatment of Heart Disease in Diabetes

If you have diabetes and develop heart disease, your doctor may recommend the following steps for treatment: 

• Changes to Your Diet: To ensure you include more fresh fruits, vegetables, lean protein, and whole grains. You would be asked to limit your intake of processed foods, foods with trans fat, sugary drinks, and alcohol.
• Regular Exercise: To improve blood sugar, blood pressure, and cholesterol levels. Exercise is also meant to decrease abdominal fat and keep your weight in a healthy range.
• Medications: To treat heart disease, including blood thinners, statins (to reduce low-density lipoprotein or ‘bad’ cholesterol), and antihypertensives (to lower your blood pressure levels)
• Surgery: In some cases, and may include coronary angioplasty, coronary artery bypass surgery, or a heart transplant. 

How to Prevent Heart Disease in Diabetes?

If you are diabetic, the best way to prevent the chances of developing heart disease is to take care of your health and lifestyle. These steps may help you keep heart disease at bay:

• Blood Sugar: Check your blood sugar levels regularly. Perform the daily blood glucose checks as well as the A1C test that shows your average blood glucose level over the past 3 months. Aim to keep your blood sugar levels within the normal range.
• Blood Pressure: Keep your blood pressure levels under control and use medications if necessary. The target blood pressure value for those with diabetes is under 130/80 mm Hg.
• Blood Cholesterol: Manage your cholesterol levels with a healthy lifestyle and medications, if prescribed by your doctor.
• Weight Management: Keep your weight in the target range, and take steps to lose weight if you are overweight or obese. These steps include a healthy diet and exercise. 
• Regular Exercise: Make regular physical activity a part of your lifestyle. Aim for at least 150 minutes of moderate-intensity aerobic exercise per week. 
• Healthy Diet: Eat a heart-healthy diet, which includes vegetables, fruits, whole grains, dairy products, healthy fats, and a variety of protein-rich foods. Limit or avoid foods with refined carbohydrates, saturated and trans fats, added sugars, and salt.
• Quit Smoking: Smoking and diabetes narrow your blood vessels, so your heart has to work harder. Quitting smoking will lower your risk for heart disease and may improve your blood glucose, blood pressure, and cholesterol levels. 
• Stress Management: Long-term stress can raise your blood glucose and blood pressure, and make you more prone to developing heart disease. Take steps to lower your stress, such as deep breathing exercises, walks, yoga, listening to music, and spending time with your loved ones. 
• Medications: Take your prescribed medications on time and do not skip them. The medicines to reduce blood pressure or blood cholesterol will protect your heart against disease.

Complications of Heart Disease in Diabetes

If left untreated, heart disease in diabetic patients can lead to serious complications including:

• Stroke: It happens when blood flow to the brain is blocked. 
• Heart Attack: It occurs when blood flow to the heart is blocked.
• Heart Failure: A chronic condition in which the heart does not pump blood as well as it should.

When to See a Doctor?

Contact a doctor immediately if you have diabetes and are experiencing one or more heart disease symptoms such as: 

• Pain or pressure in your chest for more than a few minutes
• Shortness of breath
• Fatigue
• Pain or discomfort in the arms, shoulders, abdomen, back, neck, or jaw
• Sweating
• Light-headedness
• Indigestion
• Nausea
