The Heart is a muscular organ in animals and humans, which pumps blood via the blood vessels of the circulatory system. Blood supplies the body, oxygen, and nutrients, in addition to helping in the removal of metabolic wastes. In humans, the Heart is positioned between the lungs, within the middle compartment of the chest.
The Heart pumps blood with a rhythm decided by a group of pacemaking cells within the sinoatrial node. This generates a current that causes contraction of the Heart, traveling through the atrioventricular node and alongside the conduction system of the Heart. The received blood is low in oxygen from the systemic circulation, and then goes to the right atrium by the superior and inferior venae cavae and is passed to the right ventricle. From here, it’s pumped into the pulmonary circulation, by way of the lungs where it receives oxygen and gives out carbon dioxide. Then oxygenated blood returns to the left atrium passing by the left ventricle and is pumped out by the aorta to the systemic circulation where the oxygen is metabolized to carbon dioxide — the Heartbeats at a rate close to 72 beats per minute. Exercise temporarily will increase the rate, however, lowers resting heart rate in the long run, and is better for heart health.
Cardiovascular diseases typically refer to conditions that involve narrowed or blocked blood vessels that may result in a heart attack, chest pain (angina) or stroke. Other heart conditions, similar to those that have an effect on your Heart’s muscle, valves, or rhythm, are also considered types of heart diseases. Any disease of the Heart or of the blood vessels around the Heart are called cardiovascular diseases.
Risk factors embody smoking, being overweight, little exercise, high cholesterol, high blood pressure, and poorly managed diabetes, amongst others. Cardiovascular diseases frequently don’t have symptoms or might cause chest pain or shortness of breath.
Cardiovascular diseases are the commonest reason for death globally as of 2008, accounting for 30% of deaths. Of those greater than three quarters are results of coronary artery disease and stroke.
Diagnosis of heart disease is often executed by the taking of medical history, listening to the heart sounds with a stethoscope, ECG, and ultrasound. Specialists who give attention to diseases of the Heart are known as cardiologists, though many specialties of medicine could also be involved in treatment.
Implanted Cardioverter Defibrillator– Individuals with heart failure are sometimes at risk for life-threatening, fast, irregular heartbeats referred to as ventricular arrhythmias. These individuals may have a combination biventricular pacemaker and implantable cardioverter defibrillator, or ICD, which shocks the Heart’s rhythm back to normal.
Ventricular arrhythmia happens when irregular heartbeats originate within the Heart’s ventricles, the lower chambers that pump blood to the whole body. When this occurs, the Heart stops pumping blood. If the rhythm will not be corrected shortly, the result is sudden cardiac arrest—a short-circuiting of the electrical indicators that control the Heart’s capability to pump blood.
Pacemaker– It is a small device that’s implanted under the skin of the chest. It produces electrical pulses to maintain the heart beating at a standard rate. A pacemaker helps handle heart rhythm issues, similar to bradycardia, wherein the Heartbeats too slowly, or arrhythmia in which the Heartbeats irregularly.
The size of two half-dollars pressed against each other, a pacemaker accommodates a small computer and a battery that can be connected to one or two flexible, insulated wires known as leads, extending from the device inside the chest to the Heart.
Biventricular Pacemaker– A biventricular pacemaker works like a standard pacemaker. However, it makes use of a third wire to send electrical impulses to the Heart, resynchronizing the contractions of the Heart’s left lower chamber.
Implantable Cardiac Loop Recorder– A cardiac electrophysiologist could recommend surgically implanting a wireless cardiac monitor known as a loop recorder, which repeatedly records the Heart’s rhythm for up to three years. Smaller than the dimensions of an AAA battery, the device is surgically inserted under the skin of the upper chest to record the electrical activity of the Heart, very similar to an electrocardiogram, or EKG.
The Cardiovascular Devices Market
The increasing cases of cardiovascular diseases and the growing geriatric population are the significant factors driving the growth of the cardiovascular devices market. The global market for cardiovascular devices has reached nearly $42.4 billion in 2017 and is expected to reach $59.1 billion by 2022, at a CAGR of 6.9% for the period of 2017-2022.

How to Take Care of the Heart
On average, the human heart beats for about 2.5 million times for a lifetime. It pushes gallons of blood to each part of the body. This flow carries fuel, oxygen, hormones, some other compounds, and also some essential cells. Owing to the never-ending workload of the heart, it’s amazing that it performs so well for such a long period. But despite this, we need to take care of it to keep it healthy.
Some ways in which you can maintain a Happy and Healthy Heart:
• Eat-in proper and adequate quantities. Eating more than required or less than required can affect you adversely.
• Consume lots of fruits and veggies as they are good sources of minerals and vitamins.
• Eat whole grains as they hold fiber and other nutrients helps in regulating blood pressure.
• Limit the intake of unhealthy fats or saturated or trans fats.
• Include low-fat protein sources in your diet, which are fish, lean meat, poultry, low-fat dairy products, eggs.
• Reducing the amount of sodium in food as it is a huge contributor to high blood pressure.
• Plan your diet based on the above points every day.
• Take an occasional break and treat yourself with a little guilty indulgence.
