Heart Disease

Heart pumps blood trough vessels giving oxygen and nutritive substances to body cells and clearing waste substances.
Heart disease (cardiac disorders) affects the human heart and major blood vessels. The majority of conditions associated with cardiac disorders become life threatening if left unattended. Heart disease is one of leading mortality cause in developed countries.

Heart disease can include the following: congenital heart disease, pericardial disease, arrhythmias, coronary artery disease, heart attack or heart failure, heart valve disease, heart muscle disease.
Heart disease is leading mortality cause all over the world and the number one killer in the U.S. It also more often leads to disability. There are many different forms of heart disease. You may lower your risk of heart disease by following few simple rules and taking several protective measures:

What causes heart disease

The most common cause of heart disease is narrowing or blockage of the coronary arteries that supply blood to the heart itself. This can occur due to buildup of plaque inside the artery or spasm of the artery. Plaque may begin to build up where the internal layer of artery is damaged. The buildup of plaque in the coronary arteries may start even in childhood.

After some time, plaque can solidify or tear open. Solidified plaque limits the coronary corridors and decreases the flow of oxygen-rich blood to the heart. If the plaque breaks blood cell fragments called platelets stick to the site of the injury. They may cluster together to shape blood clumps.

Blood clots can further narrow the coronary arteries. If coagulation turns out to be sufficiently huge, it can for the most part or totally obstruct a coronary vein and cause a heart assault.

This is called coronary artery disease and happens slowly over time. It's the main reason of people having heart attacks.
Other kinds of heart problems may happen to the valves in the heart, in case valves do not close completely residual blood remained in heart chambers and cause its stretching with consecutive narrowing of muscle walls thus heart may not pump well and cause heart failure. Some people are born with valve insufficiency.

Types of heart disease

Heart is one of the most vulnerable organs in the human body. There are various different types of heart disease. Some are acquired at birth, but a majority of heart diseases develop over the course of time and strike heart later in life. Below we list only few most common types of heart problems. Those are:
To summarize, there are too many types of heart disease. Some forms of heart disease may be dangerous for life. Heart diseases cannot be treated completely, so it’s really advisable to undergo heart checkups, exercise and control your diet.

Signs and symptoms of heart disease

Coronary artery disease, congestive heart failure, heart attack -- each type of heart problem has some common and some unique symptoms. Remember that if you have any of below signs – go and see your doctor to get timely treatment.

Symptoms of Coronary Artery Disease

The most common symptom of coronary artery disease is chest pain. You might feel chest pressure, discomfort, aching, burning, fullness, squeezing, or painful feeling. . Same symptoms may occur in your shoulders, hands, neck, throat, jaw, or back.

Other symptoms of coronary artery disease are shortness of breath, irregular heart beats, a faster heartbeat, weakness, nausea.

Symptoms of a Heart Attack

Symptoms of a heart attack are multiple: heaviness, nausea, anxiety, vomiting, discomfort, pressure or pain in the chest, arm, or below the breastbone, back, jaw, throat, or arm, sweating, or dizziness, or shortness of breath, fast and non – regular heartbeats.

Rapid medical assistance is very important during heart attack since it decreases damage to the heart.

Symptoms of Arrhythmias

When symptoms of arrhythmias, or an abnormal heart rhythm, are experienced they involve: fainting, and shortness of breath, "flip-flops" or pounding in your chest, , weakness or fatigue.

YouShield mobile application is designed with the purpose to help you follow up on your health, educate you about anemia symptoms, keep historical track of your lab test results and warn you if something goes wrong. YouShield provides you unique opportunity to send your health report to your doctor and request either additional lab tests or appointment as soon as the problem occurs.

What to do if YouShield warned you of heart disease risk?

If you enter any of heart disease symptoms in the YouShield application, those will be used to initiate the Heart disease health risk model assessment.

YouShield will suggest you to undergo following lab tests:

Troponin T, Creatine Kinase MB - Proteins found in striated musculature and mainly released when cardiac muscle is damaged

HGB - Hemoglobin is a protein in red blood cells that carries oxygen to the tissues so that they function effectively

Brain Natriuretic Peptide - is produced in the heart and released when the heart muscle is stretched and works hard

HDL Cholesterol - “good” cholesterol in blood

LDL Cholesterol, Direct - "bad" cholesterol in blood

Glucose, Random, Serum - Blood sugar measured randomly at any time of the day

As results of lab tests are entered into the system all available data is processed to estimate risk of certain health conditions. Simultaneously, the system provides the accuracy of this estimation, more data you enter – more accurate will be the assessment.
