There is a one out of four probability to develop Atrial Fibrillation after 40 years of age. Atrial Fibrillation implies you are five times more probable than someone without Atrial Fibrillation to die from a stroke. However, a number of other contributing variables will determine the individual danger of stroke.

You can use CHADS2 Score calculator by to assess your likelihood of stroke personally when you have been diagnosed with Atrial Fibrillation. This calculator gathers essential health data and gives you and your physician data to evaluate future therapeutic needs to decrease your danger of Atrial Fibrillation stroke. You can also take a print out from this calculator of your resultant scores.


5 Uses of CHADS2 Score Calculator

Although CHADS2 score calculator was developed for individuals with Atrial Fibrillation, some physicians believe it could work for other cardiovascular circumstances too.


Other heart diseases for prediction of which CHADS2 calculator could be used includes:

  1. Atherosclerosis
  2. Coronary Artery Disease
  3. Heart Attack
  4. Ischemic Strokes
  5. Peripheral Vascular Disease


1.    Atherosclerosis

While healthy blood Vessels are elastic in nature, they may become thickened and rigid, with time and unhealthy lifestyle decisions, and blood flow around the body may be restricted. This process is frequently referred to as arteriosclerosis and hardening of the arteries.

Atherosclerosis includes the accumulation of fatty acids and organic waste (plaques) which is a type of arteriosclerosis. It may block blood vessels partly or entirely, or it can break open and cause blood coagulation that also blocks blood flow. The body may have atherosclerosis anywhere in it.

If the atherosclerosis progression happens in your blood vessels that transports blood to the heart, Coronary Artery Disease (CAD) occurs which causes myocardial infarction or angina to be triggered.

If it happens in blood vessels which carry blood to the brain, the blood vessels become stiffened due to plaques and a blood coagulum could form and block the brain with the blood flow which causes a condition called thrombotic stroke.

In other cases, the clot may travel to other parts in the body and resided in the narrowed arteries which causes embolic stroke. Moreover, it can trigger peripheral vascular illness (PVD), if it happens in the blood vessels of your arms and fingers.

Therefore, it has been studied and we can also conclude that atherosclerosis causes all the upper mentioned diseases. So, if we use CHADS2 Score Calculator in order to predict any kind arteriosclerosis occurring in our body, we can successfully predict other cardiac diseases as well by using CHADS2 Score Calculator.


2.   Coronary Artery Disease

The most prevalent type of cardiovascular disease is coronary artery disease. It happens when one or more coronary arteries get tight or blocked. Blood is usually flowing like water as in pipes, through blood vessels.

In coronary artery disease, basically those arteries that supply blood, nutrients and O2 to the heart became damaged or diseased. This loss leads to narrowing, stiffness or blocking of blood vessels. Hardening of the arteries or atherosclerosis occurs which can easily be predicted by using CHADS2 Scoring Calculator.

Researchers had also discovered that CHADS2 can help individuals with coronary artery disease to predict the likelihood of a cardiac attack. This happens when your blood vessels are blocked and the blood and oxygen you need cannot be supplied to the heart.

Since CHADS2 scores contain comparable risk factors for coronary artery disease (CAD) growth, these results may provide key data on the severity and the risk of thromboembolism.


3.   Heart Attack

In patients with heart failure, even those without Atrial Fibrillation, scientists also claim that a version of the CHADS2 scoring used in the estimation of the danger of ischemic stroke is modestly precise to predict heart attack. CHADS2, calculates the danger of a heart attack based on possible points with greater rates of danger.

Researchers have also found CHADS2 effective for predicting strokes, thromboembolism and mortality in patients having cardiac issues without Atrial Fibrillation. The CHADS2 results were moderately predictive of these points in one year and five year follow up for all three outcome cases with heart failure, whether or not Atrial Fibrillation occurred.

4.   Ischemic Strokes (embolic and thrombotic)

The CHADS2 scoring can be used for assessing ischemic stroke risks in the communities without atrial fibrillation comprising the embolic and thrombotic subtypes in accordance with the outcomes of a latest research.

The CHADS2 Scores are used to stratify the threat of ischemic stroke in those with nonvalvular Atrial Fibrillation. Increasing the threat of ischemic stroke, both embolic and thrombotic were correlated with higher CHADS2 Score.

In community residents (non-hospitalized individuals), the CHADS2 score is used to evaluate ischemic stroke risk for non-Atrial Fibrillation. However a further investigation in future will assess whether anticoagulant use can decrease the risk of ischemic stroke in certain people that do not have Atrial Fibrillation while having a high CHADS2 levels.


5.   Peripheral Vascular Disease

Atherothrombosis is a gradual, widespread disorder that affects large or medium sized arteries across the arterial tree, with several clinically acute or chronic manifestations. Atherothrombosis in peripheral arteries causes, ischemic necrosis and potentials loss of limb, which lead to the development of peripheral arterial disease (PAD).

There is a strong risk that patients with first ischemic event will develop further atherothrombotic events. The prevalence of additional risk factors, like atrial fibrillation (AF), increases the risk of atherothrombotic events.

In patients with Peripheral Artery Disorder (PAD), stroke risk values should be evaluated using the predictive values of CHADS2. For patients with Peripheral Atrial Disease and greater CHADS2, cardiovascular risk assessment and handling is usually suggested.

Researchers have studied and observed several subjects with non-atrial fibrillation Peripheral Artery Disease diagnoses. In that study the score for CHADS2 was used to stratify the threat of 5 years of ischemic stroke from Peripheral Artery Disease.

The ischemic stroke danger for 5 years in that research was 9.4%. The Peripheral Artery Disease and CHADS2 score was observed to be strongly correlated. The score of CHADS2 was shown positive with the increase of the danger of ischemic stroke after adjustment.

Many other findings reveal that the CHADS2 score may be applied as an ischemic stroke risk indicator in patients with Peripheral Atrial Disease. So, it’s clear that we can use CHADS2 calculator for prognosis of stroke in patients with Peripheral Atrial Disease.
