  • Heart valves that are notn't functioning properly

  • Abnormal or irregular heart rhythmscardiac beats


Types of Cardiovascular Diseases

Cardiovascular diseases come in a wide variety, including but not restricted to:

  • An irregular heart rhythm or heart rate can result from an arrhythmia, a problem with your heart's electrical conduction system.

  • Heart valve illness disease refers to tightening or leakage in the valves, which allow blood to move from one heart chamber to another.

  • Coronary artery disease: Narrowing of the blood vessels An issue with the blood vessels that supply your heart., such as blockages.

  • Heart failure: Problems with the heart's pumping and relaxing mechanisms cause fluid retention and breathlessness.

  • A problem with the blood vessels in your arms, legs, or abdominal organs, such as narrowing or blockages, is known as peripheral artery disease.

  • Aortic illness can cause aortic dilatation or aneurysm.

  • Multiple heart regions are affected by congenital heart disease, which is present from birth.

  • Problems with your heart's lining, such as pericarditis and pericardial effusion, are referred to as pericardial illness.

  • Brain blood flow issues, such as blockages or vessel narrowing, are referred to as cerebrovascular illness.

  • A blockage in the veins that return blood from the body and brain to the heart is known as deep vein thrombosis (DVT).

Causes of Cardiovascular Disease

There are numerous causes of cardiovascular diseases, depending on the type. Here are a few examples: Fatty plaques in the arteries cause coronary artery disease, concerns problems with  the fetalus’s heart development cause congenital heart disease, bacteria and viruses cause heart infection, and rheumatic fever causes heart valve diseases. 

Symptoms of Cardiovascular Disease

Depending on the reason, theThe symptoms of cardiovascular disease can changemay vary depending on the cause. Women and older people may experience subtler atypical symptoms. Nevertheless, they are still susceptible to severe  cardiovascular disease.

  • High-sodium, high-sugar, and high-fat diet

  • Hyperlipidemia, or high cholesterol

  • Hypertension is a term for high blood pressure

  • Pregnancy diabetes

  • Toxemia or preeclampsia

  • Use of illegal or prescription drugs

  • Use of tobacco, including vaping

Cardiovascular Disease Complications

Complications of heart disease may include the following: 

  • Heart failure
  • Heart attack 
  • Stroke 
  • Aneurysm 
  • Peripheral artery disease
  • Sudden cardiac arrest 

 Cardiovascular Disease Diagnosis

Your healthcare professional will conduct a physical examination and inquire about your symptoms, individual health, and family medical history. They could also request testing to identify cardiovascular illness.

Typical examinations used to identify cardiovascular disease include:

  • Blood tests to evaluate elements including cholesterol, blood sugar levels, and certain proteins that signify cardiovascular health. 
  • To identify peripheral artery disease, the ankle-brachial index (ABI) analyzes the blood pressure in your ankles and arms.
  • The electrical activity of your heart is captured by an electrocardiogram (EKG).
  • Wearable gadgets are used in ambulatory monitoring to monitor your heart rate and rhythm.
  • Sound waves are used in an echocardiogram to provide an image of your heartbeat and blood flow.
  • Sound waves are used in ultrasound to examine the blood flow in your neck or legs.
  • X-rays and computer processing are used in cardiac computed tomography (CT) to produce 3D images of your heart and blood arteries.
  • Magnets and radio waves are used in cardiac magnetic resonance imaging (MRI) to provide detailed images of the heart.
  • MR angiograms and CT angiograms, which employ an MRI or CT, respectively, to view your neck, head, and leg blood arteries.
  • Stress tests examine how your heart reacts to physical exertion in a safe environment while you exercise or take drugs. EKGs and/or imaging tests may be used in this kind of test.
  • A catheter (a thin, hollow tube) is used during cardiac catheterization to assess your heart's blood flow and pressure.

Cardiovascular Disease Treatment

  • Medications: Medication may be required to control heart disease symptoms and to avoid complications if lifestyle modifications alone are ineffective. The kind of cardiac condition is what determines the medicine's kind.
