Heart Disease Facts! Trivia Questions Quiz

Excess calcium is not a risk factor for heart disease because it does not directly contribute to the development of plaque in the arteries or increase the risk of blood clots. In fact, calcium is an essential mineral for bone health and other bodily functions. However, it is important to maintain a balance and avoid excessive calcium intake, as it can lead to other health issues such as kidney stones.

This answer is correct because an electrocardiogram (ECG) is a simple test that measures and records the electrical activity of the heart. It is a non-invasive procedure that involves attaching electrodes to the skin to detect the electrical signals produced by the heart. These signals are then recorded and displayed on a graph, allowing healthcare professionals to evaluate the heart's rhythm and detect any abnormalities. A chest x-ray, physical performance test, and blood test are not methods used to detect the heart's electrical activity.

An arrhythmia refers to an irregular heart beat, where the heart may beat too fast, too slow, or in an irregular pattern. It is not specifically related to a heart attack, clogged coronary artery, or an insufficient cardiac valve. Instead, arrhythmias can occur due to various reasons such as electrical problems in the heart, heart muscle damage, or certain medications.

The correct answer is chest pain and breathlessness. Angina is a condition characterized by chest pain or discomfort that occurs when the heart muscle doesn't receive enough oxygen-rich blood. This lack of blood flow can cause a squeezing or pressure-like pain in the chest, which can radiate to the arms, neck, jaw, or back. Breathlessness or shortness of breath may also accompany the chest pain, as the heart struggles to pump enough blood to meet the body's demands.

Coronary artery disease occurs when plaques, which are made up of cholesterol and other substances, build up in the arteries that supply blood to the heart. These plaques can narrow the arteries and restrict blood flow, leading to various symptoms such as chest pain or discomfort (angina) or even a heart attack. Therefore, the correct answer is "Plaques build up and clog the arteries."

Eating healthy and being physically active are important for preventing heart disease. A balanced diet that includes fruits, vegetables, whole grains, and lean proteins can help maintain a healthy weight and reduce the risk of heart disease. Regular physical activity, such as aerobic exercises and strength training, can improve heart health by strengthening the heart muscle, lowering blood pressure, and reducing cholesterol levels. On the other hand, not taking prescribed medicine, drinking alcohol, and smoking can actually increase the risk of heart disease.

The blood vessels that cover the surface of the heart are called coronary arteries. These arteries supply oxygenated blood to the heart muscle itself, ensuring that it receives the necessary nutrients and oxygen to function properly. Without adequate blood supply through the coronary arteries, the heart muscle can become damaged or die, leading to serious health issues such as heart attack or heart failure.

Clogged coronary arteries prevent oxygen from reaching the heart, leading to a heart attack. The coronary arteries are responsible for supplying oxygen-rich blood to the heart muscle. When these arteries become blocked or narrowed due to the buildup of plaque, the blood flow to the heart is reduced or completely blocked. This deprives the heart of oxygen, causing chest pain or discomfort, and if the blockage is severe, it can result in a heart attack.

A coronary angiogram is used to diagnose coronary heart disease. It is a procedure that involves injecting a contrast dye into the coronary arteries and then taking X-ray images to visualize any blockages or narrowing in the arteries. This test helps to determine the extent and severity of the disease and can guide treatment decisions such as medication, angioplasty, or bypass surgery. Computer tomography, electroencephalogram, and blood count are not specific tests for diagnosing coronary heart disease.

The average heart rate for a healthy adult is around 60-100 beats per minute. Therefore, the correct answer of 70 times falls within this range and is a reasonable estimate for the number of times a heart beats in a minute.
