What distinguishes a heart attack from a stroke?

Today the death rate from heart attack or stroke increases and the age decreases. Today, no heart attack, no stroke, not insured by any elderly man or a teenager or even a child. Each of these diseases in its own way dangerous, is a serious complication and often threatens the patient’s life or lead to disability. To prevent this, you need to know the causes of diseases and preventive measures.

What distinguishes a heart attack from a stroke?

Both these diseases are at the basis of the occurrence have pathology of blood vessels. The difference is in the consequences and in the organs that are affected. A heart attack can occur in the heart muscle, renal tissue in the spleen. A stroke is a condition found only in brain tissue. To understand that is worse for the body, you need to understand the mechanism of each disease. The basis of the occurrence of a heart attack is the death of the body as a result of sudden cessation of oxygen and nutrients to the tissues. Causes of heart attack can be:

  • Atherosclerosis. This disease is accompanied by deposition of atherosclerotic plaques on the inner wall of the vessel, leading to blockage of its lumen and cessation of blood flow through this vessel.
  • A thrombosis (obstruction of its lumen by thrombus or embolus). In addition to the thrombus, the vessel can get clogged by a drop of fat or air. As a result of thrombosis by the same termination mechanism of oxygen through the vessel to the tissues.
  • Stenosis (narrowing) of the vessel. Causes of stenosis are a lot, the result is the same – oxygen starvation of the body that nourishes this vessel. Any increase in physical exertion, or stress can provoke the escalation of stenosis and lead to a heart attack.

A stroke, in fact, it is also a violation of tissue of the brain due to cessation of oxygen supply to that part. Reasons may be:

  • the blood clots, the sharp narrowing of the vessel – this option is called ischemic stroke;
  • the rupture of the vessel and exit of blood in the brain tissue, in this case hemorrhagic stroke.

Regardless of what happened in the body – a heart attack or stroke, function of the affected organ is sharply violated, the tissues die. Often the body brings balance to the entire body, which leads to the death of the patient.

What is more dangerous, a heart attack or stroke?

Each of the diseases with serious complications. Each of the complications may lead to death. To understand what worse effect on the body, you need to know the complications of these diseases. Myocardial infarction may be complicated by the following conditions:

  • Violations heart rhythm (arrhythmia). Can meet acceleration (tachycardia), slow (bradycardia) or uneven cuts (atrial fibrillation).
  • Acute or chronic heart failure is a significant decrease in functional ability of the heart, which can lead to stagnation of blood in the vessels, pulmonary edema, cardiac asthma, etc.
  • Cardiogenic shock is a condition that affects the whole body. The patient experiences severe pain, blood pressure drops to critical numbers, the heart slows down its activity. This is the most frequent of the complications that lead to death.
  • Rupture of the heart muscle as a result of deterioration of heart tissue and death of its plot occurs violation of the integrity of the muscular wall, which is 10% leads to death of the patient.

Stroke entails the withering away (in the worst case) or disability (at best) part of the brain. Each of the parts of the brain responsible for specific functions in the body, respectively, in stroke, these functions are impaired. Complications after stroke can be:

  • Paresis and paralysis is a violation of motor function of muscles. The patient may lose the ability to swallow, speak, walk, write, shift items from hand to hand, etc.
  • Pneumonia (pneumonia) – occurs as a result of a prolonged stay in the supine position, leading to stagnation and inflammation.
  • Coma is a prolonged unconsciousness of the patient. He ceases to react to external stimuli and pain. Often this complication ends with the withering away of the greater part of the brain. In this case, the patient dies, never regaining consciousness.
  • Dementia – decrease in mental abilities.
  • Disruption or complete loss of memory.
  • Pain in the side of the torso, the limbs or a sensation of numbness, tingling, loss of sensation in certain areas of the body.
