Can lack of oxygen cause a heart attack?
What causes most strokes?
What are the signs of not enough oxygen?
Common symptoms include:
The prognosis for heart attacks is somewhat worse than strokes, as heart attacks are the leading cause of death in the US.
How do I know if Im not getting enough oxygen to my heart?
Leading risk factors for heart disease and stroke are high blood pressure, high low-density lipoprotein (LDL) cholesterol, diabetes, smoking and secondhand smoke exposure, obesity, unhealthy diet, and physical inactivity.
Heart Disease: when the heart does not receive enough oxygen due to coronary artery disease or other conditions, parts of the heart may be damaged. Symptoms can range from shortness of breath, fatigue and dizziness to heart arrhythmia, palpitations and angina.
A heart attack, or myocardial infarction, is a medical emergency in which the supply of blood to the heart is suddenly and severely reduced or cut off, causing the muscle to die from lack of oxygen.
The brain is an organ that cannot store oxygen, so blood vessels deliver oxygen through the blood. A lack of blood supply can cause a stroke, therefore causing surrounding nerve cells to be cut off from nutrients and oxygen. If the brain tissue lacks oxygen for more than three or four minutes, the tissue begins to die.
Myocardial ischemia can lead to serious complications, including: Heart attack. If a coronary artery becomes completely blocked, the lack of blood and oxygen can lead to a heart attack that destroys part of the heart muscle. The damage can be serious and sometimes fatal.
