DAPT Calculator

The DAPT calculator provides information on anticoagulant doses and treatment guidelines for patients who are taking the medications. This article can help you to better understand what a DAPT calculator is, how can you use it, what are advantages and disadvantages? You have all that information in the text below. Of course, this tool will never replace the professionalism of the professional staff, but we certainly try to be as clear and reliable as possible.

We recommend you to look at other calculators in the field of medicine, which can help you to e.g. calculate the consumption of cigarettes annually and reduce their use or to calculate how much you need to reduce cholesterol in order for your health to be grateful for it.

What is a DAPT?

Small particles pass through our blood, the accumulation of which can cause blood clots. These particles are platelets. In most cases, these blood clots can cause a heart attack, but they can also lead to stent coagulation. In this case, there are drugs, so-called antiplatelet agents, that prevent platelet aggregation and the possible occurrence of blood clots.

Furthermore, patients who want to avoid the occurrence of stroke and heart attack are treated with two types of antiplatelet agents that prevent the occurrence of clots. So, this is DAPT (Dual Antiplatelet Therapy).

Dual Antiplatelet Therapy – Benefits and Side-effects

The two antiplatelet drugs in dual antiplatelet therapy are aspirin and clopidogrel. Aspirin is an NSAID that helps prevent blood clots from forming. Clopidogrel is a platelet aggregation inhibitor that prevents platelet aggregation. These two drugs work together to prevent clots from forming and help dissolve any lumps. You can use clopidogrel daily, and aspirin is taken when needed to avoid a heart attack or stroke. Therefore, both drugs have side effects, including stomach upset, bleeding, and tinnitus.

 Advantages of dual antiplatelet therapy are:

• reduces the risk of heart attack or stroke,
• reduces the risk of clots,
• helps prevent the formation of clots in the lungs,
• supports to avoid the formation of blood clots in the arteries, 
• helps prevent the appearance of blood clots in the brain,
• helps prevent blood clots in the legs,
• reduces the risk of other heart attacks.

In fact, the side effects of dual antiplatelet therapy are less common than the benefits, but they exist. The most common side-effect is bleeding, which may occur with or without a medical procedure. In the same way, bleeding may be more likely to occur in those taking an anticoagulant, a blood thinner. For this reason, patients on antiplatelet therapy should tell their doctor about any bleeding or bruising that happens.

DAPT Score – Definition and Interpretation

DAPT Score measures the probability of a first major cardiovascular event. Therefore, you can use it to determine the risk of recurrent heart attack, stroke, or death. With the help of the DAPT score, you can determine the duration of dual antiplatelet therapy using aspirin after coronary intervention (PCI) with stents.

When we talk about this, it is crucial to emphasize the danger of possible bleeding in this case. With the continued use of this therapy, it is necessary to assess the relationship between reduced ischemia and the possible occurrence of increased bleeding.

DAPT Score Formula

DAPT Score Formula is based on the following factors:

1. Age
2. Diabetes mellitus?
3. Prior MI or PCI?
4. MI at presentation
5. Stent diameter < 3 mm?
6. Vein graft stent?
7. History of CHF or LVEF <30%
8. Current or past smoker?
9. Paclitaxel-Eluting stent?

One point is granted to most sections if yes or no. In a situation where CHF or LVEF < 30% and stent venous graph, if the answer is “yes,” that means two points. To illustrate, points are ranked based on the patient’s age:

Here is how to create a DAPT score that ranges from -2 to 10:

• If the patient benefits from DAPT, and not just from aspirin, it is considered a high result, and it represents 2 or more points.
• If aspirin is successful, without DAPT, it is considered a low result, and it represents 1 point or less.

DAPT Calculator – Example

Using this calculator is easy and will give you results very quickly. After reading this article, you could find out what DAPT is. You can use this calculator as follows:

In addition, the calculator offers you the ability to choose the age of the patient. Then fill in the fields provided or answer the questions with “Yes” or “No.” Once you do that, the result will be at the bottom, and that is it. In the picture below, you can find how we came to the DAPT results effortless way with all the fields matched.

DAPT Calculator: Real-world application

The use of the DAPT calculator is helpful for diabetes patients with prescription. For this purpose, we can say that DAPT is also a type of medication that lowers blood sugar levels. You can use a calculator to determine the amount of DAPT needed to achieve your desired blood sugar level. The calculator has two parts, one with which you can choose the starting dose and adjust the quantity. 

For instance, you can pick the starting dose based on the patient’s weight, blood sugar levels, and whether he is taking insulin. The patient enters their weigh and weight blood sugar level, and if they take weight insulin into the calculator, the calculator would then recommend the appropriate initial dosage. 

The calculator will also show the patient how much DAPT they will need to take to maintain their desired blood sugar level. For example, if a patient has a blood sugar level of 160 mg/dL and is not taking insulin, the calculator will recommend an initial dosage of 25 mg. If the patient is trying to maintain a blood sugar level of 100 mg/dL, they will need to take 25 mg every 8 hours.
