Can I drink coffee before an echocardiogram?

In this text we will answer the question: “Can I drink coffee before an echocardiogram?”. In addition, we will discuss a little about the exam procedures and the relationship between the habit of drinking coffee and heart health.

Can I drink coffee before an echocardiogram?

You should avoid exciting drinks in the 24 hours before the test, such as coffee, tea, alcohol and soda.

The echocardiogram is a simple exam that serves to evaluate, in real time, some characteristics of the heart, such as size, shape of the valves, muscle thickness and the heart’s ability to function, in addition to blood flow. 

This exam also allows you to see the state of the great vessels of the heart, pulmonary artery and aorta at the time the exam is being performed.

This exam is also called echocardiography or ultrasound of the heart, and has several types, such as one-dimensional, two-dimensional and with Doppler, which are requested by the doctor according to what you want to evaluate.

The echocardiogram is a simple procedure that requires no preparation, with the exception of the transesophageal echocardiogram, in which it is recommended that the person does not eat for about 3 hours before the exam.

This test is usually done in the cardiologist’s office or an imaging clinic, and takes 15 to 20 minutes.

Depending on the purpose of the exam, different echocardiograms can be performed, the main ones being:

  • Transthoracic echocardiogram: this is the most commonly performed test, in which the equipment is placed in the thoracic region.
  • Fetal echocardiogram: performed during pregnancy to evaluate the baby’s heart and identify diseases
  • Doppler echocardiogram: especially indicated to assess blood flow through the heart, especially useful in valvular heart disease
  • Transesophageal echocardiogram: is indicated to also evaluate the esophageal region in search of diseases.

What is needed to perform a transesophageal echocardiogram?

In general, no preparation is required before the exam for adults. However, there are two types of echocardiogram that need preparation: the transesophageal echocardiogram and the stress echocardiogram. It is necessary to observe the preparation recommendations.

In transesophageal echocardiography, a 6-hour fast is required to avoid nausea and vomiting. Already in the stress echocardiogram, it is recommended not to eat anything heavy to avoid nausea. In addition, the ideal is to wear clothes that allow the practice of exercises. Remembering that the echocardiogram is a simple, quick test that does not use radiation.

Is coffee bad for the heart?

Studies show that the association between caffeine consumption and the consequent effects on atrial and ventricular arrhythmias is related to the amount of consumption. That is, in correct doses, it is possible that coffee is good for heart health.

The recommended consumption per day is 250 milligrams or the equivalent of two espresso coffees. The maximum consumption of caffeine per day is 400mg or 3 cups of coffee. 

However, it is important to emphasize that this value should only be a reference, since the indexes vary according to the personal characteristics of each one. This is because, in addition to caffeine being associated with body weight, each organism has a certain sensitivity to the substance.

However, the habitual consumption of coffee leads to the development of tolerance which contributes to the effect of raising the pressure. 

That is, in individuals who already have the habit of consuming coffee, the drink raises blood pressure slightly. In general, the recommendation is that the ideal intake of coffee consists of two to three cups a day for healthy individuals.

What are the benefits of coffee?

Coffee has a number of medicinal properties, such as:

  • Appetite inhibition
  • Cardio stimulants
  • Diuretics
  • Laxatives
  • Muscle relaxants
  • Vasoconstrictors

In addition, it is able to reduce the symptoms of constipation, fatigue, migraine, asthma, obesity and paralysis, in addition to relieving pain. Coffee is also used to enhance the effect of other substances present in the body, providing a huge sense of well being.

It also improves respiratory congestion, opens bronchial passages and speeds up metabolism, leading to weight loss as it increases the number of calories burned. Another important property of coffee is to stimulate the liver and bowel cleansing.

Considering what the scientific literature has brought us so far, caffeine in moderate doses (100 to 200 mg) has benefits for the heart. However, caution is required in two situations:

If the person has a family history of hypertension and cardiovascular disease and when the individual has a cardiovascular or metabolic risk factor, and without medical consultation, he ingests caffeine before performing a physical effort.

So caffeine can be good or bad for the heart, depending on the context.
