Cardiovascular Diseases

Of all the diseases here in NZ, cardiovascular disease is one of the most common occurrences to people. Cardiovascular diseases are also known as implications in the heart. It is either there is wrong with your heart or in your blood vessels that are responsible for carrying oxygen and nutrients to your body to keep it working.

According to the statistics of the website https://www.heartfoundation.org.nz/statistics (go check it out for more in for more info about heart diseases!), there are 186,000 people that are living with heart diseases. And there are many types of cardiovascular diseases. Listing:

  • Coronary artery disease ( this is caused by atherosclerosis explained below)
  • Heart failure ( mostly mistaken as when the heart stopped working but no, it is when the heart isn't pumping and providing enough blood and oxygen)
  • Arrhythmias ( this when a person experience abnormal heartbeat, either fast or slow beat of the heart)
  • Heart Valve diseases ( when the valves in the heart don't open properly which cause the flow of blood to be improper)
  • Heart Attack ( this happens when the blood clot blocks the arteries and discontinue blood from flowing and the certain part of the heart muscle that's supplied by the arteries, begin to cease)

Most of heart diseases are caused by what we call atherosclerosis. Atherosclerosis is when the plaque (fatty deposits that are made up of cholesterol, fatty substances, cellular waste products, calcium, and fibrin) build up in the artery walls and restrain blood from flowing to the heart and brain.

Symptoms (fully credits to the website https://www.mayoclinic.org/diseases-conditions/heart-disease/symptoms-causes/syc-20353118)

Symptoms of heart disease in your blood vessels (atherosclerotic disease)
Cardiovascular disease symptoms may be different for men and women. For instance, men are more likely to have chest pain; women are more likely to have other symptoms along with chest discomforts, such as shortness of breath, nausea and extreme fatigue.


  • Chest pain, chest tightness, chest pressure and chest discomfort (angina)
  • Shortness of breath
  • Pain, numbness, weakness or coldness in your legs or arms if the blood vessels in those parts of your body are narrowed
  • Pain in the neck, jaw, throat, upper abdomen or back
  • You might not be diagnosed with cardiovascular disease until you have a heart attack, angina, stroke or heart failure. It's important to watch for cardiovascular symptoms and discuss concerns with your doctor. Cardiovascular disease can sometimes be found early with regular evaluations.


Heart disease symptoms caused by abnormal heartbeats (heart arrhythmias)
A heart arrhythmia is an abnormal heartbeat. Your heart may beat too quickly, too slowly or irregularly. Heart arrhythmia symptoms can include:


  • Fluttering in your chest
  • Racing heartbeat (tachycardia)
  • Slow heartbeat (bradycardia)
  • Chest pain or discomfort
  • Shortness of breath
  • Lightheadedness
  • Dizziness



Heart disease symptoms caused by valvular heart disease
The heart has four valves — the aortic, mitral, pulmonary and tricuspid valves — that open and close to direct blood flow through your heart. Valves may be damaged by a variety of conditions leading to narrowing (stenosis), leaking (regurgitation or insufficiency) or improper closing (prolapse).

Depending on which valve isn't working properly, valvular heart disease symptoms generally include:


  • Fatigue
  • Shortness of breath
  • Irregular heartbeat
  • Swollen feet or ankles
  • Chest pain
  • Fainting (syncope)
  • When to see a doctor
  • Seek emergency medical care if you have these heart disease symptoms:
  • Chest pain
  • Shortness of breath
  • Fainting
  • Heart disease is easier to treat when detected early, so talk to your doctor about your concerns regarding your heart health. If you're concerned about developing heart disease, talk to your doctor about steps you can take to reduce your heart disease risk. This is especially important if you have a family history of heart disease.



If you think you may have heart disease, based on new signs or symptoms you're having, make an appointment to see your doctor.
