Heart Blocks are a result of plaque buildup in your arteries, which blocks blood flow and circulation to the heart, causing heart muscle damage and heightens the risk for heart attack and stroke.
Arteries which have smooth and elastic walls become thick and restrict blood flow from the cholesterol deposits over the years. Blood clots can also block the arteries that supply oxygen rich blood to the heart. These can eventually lead to strokes and heart attacks.

Some warning signs that you may be at risk of heart blockage:

1. Have you had a mild stroke: Plaque that accumulates in the carotid artery supplying oxygen rich blood to the brain can cause a stroke. People who have had strokes are more prone to heart attacks.
2. Do you often feel fatigue and dizziness: Reduced oxygen from poor circulation and blood flow can result in fatigue and tiredness as well as dizziness.
3. Experiencing shortness of breath: Poor blood flow can lead to shortness of breath from even mild forms of exercise or even from carrying out daily chores or walking.
4. Sudden chest pain: Chest pain or angina result from reduced supply of blood to the heart. It can be felt as pressure, tightness in the chest, squeezing in the chest, numbness or burning.
5. Unexplained lower back pain: This can result from pressure in the spine as a result of pinched nerves due to compressed vertebrae discs as a result of poor blood flow.
6. Erectile dysfunction in men: If an erection becomes difficult or impossible, it could be a warning sign of clogged arteries. These arteries supply blood to the pelvis area and help achieve an erection.
7. Calf pain: Blocked leg arteries can cause calf pain, especially in smokers . THis is an early sign of possible heart blocks.
8. Painful, numb and cold hands and feet: Plaque build up in the arteries of the extremities can cause numbness and coldness in the hands and feet. If you wish to discuss about any specific problem, you can consult a Cardiologist.

For a long time cholesterol in totality was seen as a bad thing for your body although the truth was a little more complicated than that. Cholesterol primarily is divided into two types, one of which can be categorized as bad cholesterol and the other as good cholesterol. Let's have an in-depth look at both the categories.

LDL or Low Density Lipoprotein aka bad cholesterol: Cholesterol is a wax like chemical which is found all over the body and it has important functions to perform. Cholesterol is carried all over the body by Lipoproteins. The low density lipoproteins are denoted as bad cholesterol as they can accumulate on the walls of the blood vessels and cause blockages resulting in many ailments. LDL levels of 190 and above are considered dangerous. 

Some of the risks associated with it are:

1. Heart disease
2. Stroke
3. Atherosclerosis
4. peripheral artery disease among many others

HDL or High Density Lipoprotein aka good cholesterol: This is a form of cholesterol which is usually desired in higher quantities as it removes LDL from the system by dislodging it from the arteries and then carrying it through the bloodstream into the liver. The liver then breaks it down and removes it from the body. Thus, higher number of HDL cholesterol is always desirable. Some of the ideal numbers for HDL cholesterol within the body are:

For Women  - Ideal: 60 mg/dl, dangerous: 50 mg/dl or lower
For Men - Ideal: 60 mg/dl, dangerous: 50 mg/dl lower

The role of triglycerides:
Good and bad cholesterol levels also depend on the levels of triglycerides within the body and not just LDL or HDL cholesterol. Triglycerides are another type of fat which are used to store energy within the body, but can also affect your health. It is most associated with atherosclerosis when the levels of triglycerides are high within the body. 

Some habits that contribute to high levels of it are:

• Lack of physical activity
• Obesity or being overweight
• Excesses in alcohol consumption
• Smoking
• Bad diet and others

Thus the good cholesterol vs bad cholesterol war also includes other factors, most of which can be easily changed by making subtle changes in lifestyle and incorporating healthier habits. This will increase the good cholesterol and the other relevant elements and reduce the bad.
