Cardiovascular diseases (CVDS)
Cardiovascular diseases comprise ailments that include the blood vessels (veins, arteries and capillaries) or the heart, or together or diseases that disturb the cardiovascular system.
The cardiovascular system, also named as the circulatory system, is the system that transports blood all over the human body. It is composed of the heart, arteries, veins, and capillaries. It delivers oxygenated blood from the lungs and heart through the entire body by the arteries. Blood drives through the capillaries - vessels located between the veins and arteries.
When the blood has been worn-out of oxygen, it makes its way back to the heart and lungs through the veins. The circulatory system might also comprise the circulation of lymph, which is basically recycled blood plasma once it has been filtered

Angina is chest throbbing or discomfort produced when heart the muscle doesn't acquire sufficient oxygen rich blood. It may appear like heaviness or squeezing in your chest. The anxiety also can occur in your shoulders, arms, neck, jaw or back. Angina pain may even feel like dyspepsia. But, angina is not a disease. It is a indication of an primary heart problem, generally coronary heart disease (CHD).
Arrhythmia:
An arrhythmia defines an unbalanced heartbeat the heart may beat too fast (tachycardia), too slowly (bradycardia), too promptly (premature contraction), or irregularly (fibrillation). Arrhythmias arise when the electrical indicators to the heart that manage heartbeats are not working appropriately. Several heart arrhythmias are not hurtful. Some individuals practice irregular heartbeats, which may feel comparable to a racing heart or trembling. Though, if they are mainly atypical, or result from a fragile or impaired heart, arrhythmias can root serious and even potentially deadly symptoms.
Congenital heart
Annexe 1 : Heart murmur 1. An unusual sound coming from the heart that can be detected by a stethoscope. These noises are caused by an abnormal turbulence produced when blood flows across one of the heart (valves, cardiac chambers) and or vessels close to the heart Heart murmurs are classified by the intensity of the sound heard: Stage I (murmur is of low intensity and can hardly be heard) to Stage VI (murmur is extremely loud).
Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Hannah Bunce Fayetteville Technical Community College Angina, Myocardial Infarction, and Cardiac Arrest Comparison and Contrast Three of the most commonly occurring cardiac related events: angina, myocardial infarction, and cardiac arrest, are commonly confused. However, there is a huge difference between each of them. It is crucial to be informed of each of these cardiovascular emergencies and to be able to differentiate between them. As a medical professional it is also very important to know the appropriate care for each these cardiac related emergencies.
1.Congestive Heart Failure also known as (heart failure) is a life threatening condition. Heart Failure is caused when someone has a weak heart. It usually happens when the bodies blood pump to the heart is not pumping blood to the heart correctly.
A person may be tired with doing daily activities such as shopping, climbing stairs, or simply just walking. This happens because the heart cannot pump enough blood to supply the tissues. One of the biggest symptoms is an increased heart rate. This may feel like the heart is throbbing, or racing. This happens because the heart is trying to catch up to the pumping capacity, causing the heart to beat so much faster.
You develop difficulty breathing, chest pain, a racing heart beat, or heart palpitations. These symptoms may represent a serious problem that is an emergency. Do not wait to see if the symptoms will go away. Get medical help right away. Call your local emergency services (911 in the U.S.).
Introduction to Atrial Fibrillation The most prevalent clinical arrhythmia is atrial fibrillation, which can be defined as irregular heart beats caused by uncoordinated activation of the atria. Atria are the two upper chambers of the heart. During atrial fibrillation, the cardiac muscles that make up the walls of these atrial chambers, receive disorganized activation signals. This causes them to fibrillate, which means rapid and irregular contractions. This results in inefficient pumping of blood from the atria into the ventricles, the lower two chambers.
AFib treatment options vary depending upon the severity of the disease and the underlying reasons or diseases that caused it to occur. Atrial fibrillation, also known as AFib, must be treated on a case-by-case basis in order to reduce the risk of other health problems or complications. Understanding AFib AFib occurs when the uppermost chambers of the heart beat irregualry and uncoordinated with the lower two chambers. AFib often causes a fast heartbeat that is irregular, chest pain, difficulty breathing, heart palpitations, weakness and dizziness. AFib episodes may happen sporadically or become chronic and occur regularly.
Innocent Heart Murmur, Pediatric A heart murmur is an unusual or abnormal sound that is heard during a heartbeat. The sound comes from blood passing through the heart 's chambers, valves, and blood vessels. There may be a “hum” or “whoosh” sound that is heard when the heart beats. There are two types of heart murmurs: • Innocent heart murmurs.
Carditis is an inflammation of the heart. 19. Atherosclerosis is a condition where the arteries are blocked with plaque and the blood flow decreases. This can cause heart attacks and strokes. 20.
Atherosclerosis is a disease of the arterial wall. Susceptible sites of the artery become stenosed by lipid retention. This lipid retention causes arthersclerotic lesions that can cause ischemia which can trigger occlusions of major conduit arteries of the heart, brain, legs and other vital organs. These lesions begin in the inner lining of the arteries and progress eventually effecting the entire wall. The rate of plaque formation is the same regardless of race, ethnicity, sex or geographic area.
Normally there’s a problem valve that makes your heart beat faster. (American Heart Staff “What are Heart Murmurs?”). This forces your heart to work harder than normal; however, this is fortunately not considered a disease and they’re normally harmless. (WebMD staff “Heart Murmur”). Doctors most often find these at annual check ups.
I began to notice pains in my heart from time to time and notified my mom who, in my opinion, overreacted. Turned out that I had a slight heart murmur which is kind of like getting cramps in one of the most important organs in your
That means a fast heartbeat can make your heart work harder and can increase the risk of heart disease more than people who always be given
Symptoms of panic attacks can include dizziness, choking, trembling, shortness of breath, irregular heartbeat, and chest pains. However, different people can experience slightly different symptoms (Meyers & DeWall, 2015). One woman described her panic attack saying it made her feel very hot and like she could not breathe. Her heart was racing and she felt sweaty as if she were going to faint.
The cardiovascular system is the heart and it is a four-chambered pump that carries blood to the arteries these arteries then carries out clean and oxygenated blood to the tissue. The blood Definition According to (dictionary.com 2002). Blood is the fluid that circulates in the vascular system of human beings and, in a humans blood is consisting of plasma in which the red blood cells, white blood cells and platelets are suspended.
