Total Cholesterol

A cholesterol level above 200mg/dl is considered high. That is why you should pay attention to it. However, bear in mind the ratios to have a better understanding of your whole situation. If the high number is due to HDL (the "good" cholesterol), things might be not that bad.

A cholesterol level behind 200mg/dl is considered healthy. You should have in mind that in the last years, the level considered healthy has been lowered. However, it is important to check your ratios: if you have a low proportion of "good" cholesterol (HDL) against the "bad" low-density lipoproteins (LDL and triglycerides), you may need to change some habits.

Castelli Risk Index

The Castelli Risk Index (CRI) helps you understand your atherosclerosis riks. It shows the ratio between HDL ("good" cholesterol) and the total cholesterol. "Good" cholesterol is believed to counteract against the "bad" one, which raise your risk for heart disease and stroke. Higher numbers show a higher risk. Above 4.5, you are at risk but you still can control it.

Everything it good here. A low risk index means that you are protected against coronary heart disease (CHD), because your levels of "bad" fat are not that high, when compared to the "good" cholesterol (HDL).

Your risk index is grade II, that means, between 4.6 and 5.5. It is higher than a healthy level, and you should take action. The ratio of the "good" cholesterol (HDL) is low, which means that most part of your total cholesterol is the "bad one", and there is little room for HDL, which is believed to counteract the bad fat. Get medical advice.

Your risk index is grade III (higher than 6.5), the highest one. The situation is critical, because most part of your blood cholesterol is the "bad" one. You are at risk of suffering a heart attack or a stroke. A doctor should prescribe you drugs and give you advice about healty habits.


This index shows the ratio between "bad" cholesterol (LDL) and "good" cholesterol. This index focus solely on that ratio, without considering other blood lipoproteins. It is a good tool to understand your cholesterol balance. Above a level of 3, you are at risk.

A ratio level below 3 means that the risk is low. Your high amount of "good" cholesterol (HDL) when compared to "bad" cholesterol (LDL) is protecting you against the negative impact of low-density lipoproteins. Still, bear in mind the other indexes in order to have a full picture.


We strongly recommend that you see a doctor as soon as possible to get professional advice. Every available index show that you are at risk, and you might need drug therapy. You need to change your habits now: get more excercise and less fat in your diet. Some extra "good" cholesterol might help: omega fatty acids, oatmeal (because of it soluble fiber), almonds, nuts, etc.

Your are out of danger. All your levels are completely healthy, by their own and all together, in every type of index.
