Clinical Classification

Clinical Information

  • Cardiomegaly

    enlargement of the heart, usually indicated by a cardiothoracic ratio above 0.50. heart enlargement may involve the right, the left, or both heart ventricles or heart atria. cardiomegaly is a nonspecific symptom seen in patients with chronic systolic heart failure (heart failure) or several forms of cardiomyopathies.
  • Cardiomegaly, Exercise-Induced

    non-pathological heart enlargement and other remodeling in cardiac morphology and electrical circuitry found in individuals who participate in intense repeated exercises.
  • Left Ventricular Hypertrophy

    enlargement or overgrowth of the myocardium of the left ventricle, due to chronic pressure overload.
  • Left Ventricular Hypertrophy by ECG Finding|LEFT VENTRICULAR HYPERTROPHY|Left Ventricular Hypertrophy|Left Ventricular Hypertrophy by EKG Finding

    an electrocardiographic finding suggestive of a hypertrophied left ventricle, characterized by large qrs amplitudes and secondary findings of left atrial enlargement, left axis deviation, or typical pattern of st depression and t wave inversion. (cdisc)
  • Left Ventricular Hypertrophy with Strain

    a finding of left ventricular hypertrophy based on the analysis of diagnostic metrics that may indicate a higher risk for cardiovascular events.
  • Left Ventricular Hypertrophy with Strain by ECG Finding|LEFT VENTRICULAR HYPERTROPHY WITH STRAIN|Left Ventricular Hypertrophy With Strain|Left Ventricular Hypertrophy with Strain by EKG Finding

    an electrocardiographic finding suggestive of a hypertrophied left ventricle, characterized by large qrs amplitudes, st depression and t wave inversion. (cdisc)
  • Voltage Criteria Suggesting Left Ventricular Hypertrophy, Without Secondary ECG Findings|VOLTAGE CRITERIA SUGGESTING LEFT VENTRICULAR HYPERTROPHY, WITHOUT SECONDARY ECG FINDINGS

    an electrocardiographic finding of large qrs amplitudes that may indicate left ventricular hypertrophy, but is without any of the secondary findings that are typically seen with this diagnosis: left atrial enlargement, left axis deviation, or typical pattern of st depression and t wave inversion.
  • Right Ventricular Hypertrophy

    enlargement or overgrowth of the myocardium of the right ventricle, due chronic pressure overload.
  • Right Ventricular Hypertrophy by ECG Finding|RIGHT VENTRICULAR HYPERTROPHY|Right Ventricular Hypertrophy by EKG Finding|Right ventricular Hypertrophy

    an electrocardiographic finding suggestive of a hypertrophied right ventricle, characterized by large r wave amplitudes in the right precordial leads and secondary findings of right atrial enlargement, right axis deviation, and typical pattern of st depression and t wave inversion in the right precordial leads. (cdisc)

Patient Education


Heart Diseases

What is heart disease?

Heart disease is a general term that includes many types of heart problems. It's also called cardiovascular disease, which means heart and blood vessel disease.

Heart disease is the leading cause of death in the United States, but there are ways to prevent and manage many types of heart disease.

What are the types of heart disease?

There are many different types of heart disease. Some you may be born with, called congenital heart disease. Other types develop during your lifetime.

Coronary artery disease (also called coronary heart disease) is the most common type of heart disease. It happens slowly over time when a sticky substance called plaque builds up in the arteries that supply your heart muscle with blood. The plaque narrows or blocks blood flow to the heart muscle and can lead to other heart problems:

  • Angina - chest pain from lack of blood flow
  • Heart attacks - when part of the heart muscle dies from loss of blood flow
  • Heart failure - when your heart can't pump enough blood to meet your body's needs
  • Arrhythmia - a problem with the rate or rhythm of your heartbeat

Other types of heart diseases may affect your heart valves or heart muscle (cardiomyopathy).

What causes heart diseases?

The causes of heart disease depend on the type of disease. Some possible causes include lifestyle, genetics, infections, medicines, and other diseases.

Who is more likely to develop heart diseases?

There are many different factors that can make you more likely to develop heart disease. Some of these factors you can change, but others you cannot.

  • Age. Your risk of heart disease goes up as you get older.
  • Sex. Some factors may affect heart disease risk differently in women than in men.
  • Family history and genetics. A family history of early heart disease raises your risk of heart disease. And research has shown that some genes are linked to a higher risk of certain heart diseases.
  • Race/ethnicity. Certain groups have higher risks than others.
  • Lifestyle habits. Over time, unhealthy lifestyle habits can raise your risk heart disease:
    • Eating a diet high in saturated fats, refined carbohydrates, and salt.
    • Not getting enough physical activity.
    • Drinking too much alcohol.
    • Smoking and exposure to secondhand smoke.
    • Too much stress.
  • Having other medical conditions can raise your risk of heart diseases. These conditions include:
    • High blood pressure.
    • High cholesterol levels.
    • Diabetes.
    • Obesity.
    • Autoimmune and inflammatory diseases.
    • Chronic kidney disease.
    • Metabolic syndrome.

What are the symptoms of heart disease?

Your symptoms will depend on the type of heart disease you have. You may not have symptoms at first. In some cases, you may not know you have heart disease until you have a complication such as a heart attack.

How are heart diseases diagnosed?

To find out if you have heart disease, your health care provider will:

  • Ask about your medical history, including your symptoms
  • Ask about your family health history, including relatives who have had heart disease
  • Do a physical exam
  • Likely run heart tests and blood tests

In some cases, your provider may refer you to a cardiologist (a doctor who specializes in heart diseases) for tests, diagnosis, and care.

What are the treatments for heart disease?

Treatment plans for heart disease depend on the type of heart disease you have, how serious your symptoms are, and what other health conditions you have. Possible treatments may include:

  • Heart-healthy lifestyle changes
  • Medicines
  • Procedures or surgeries
  • Cardiac rehabilitation

Can heart diseases be prevented?

You may be able to lower your risk of certain heart diseases by making heart-healthy lifestyle changes and managing any other medical conditions you have.

Footnotes

[1] Chronic - a chronic condition code indicates a condition lasting 12 months or longer and its effect on the patient based on one or both of the following criteria:

  • The condition results in the need for ongoing intervention with medical products,treatment, services, and special equipment
  • The condition places limitations on self-care, independent living, and social interactions.
