Blood tests can identify heart disease risk factors, including unhealthy cholesterol and raised blood sugar, before you notice symptoms. Combined with blood pressure checks, family history, and a medical assessment by a clinician such as a Heart Specialist, they help guide prevention. They cannot confirm that your arteries are clear or predict exactly when a heart attack might happen. Their value lies in helping you act on risks earlier.
Personal fitness is always secondary when parents have to drive kids to school, attend to work, and go on with other people's schedule. Being in good shape allows putting off a visit to the doctor once again. However, some serious cardiovascular hazards may arise unnoticed.
Why Feeling Fine Does Not Tell the Whole Story
According to the World Health Organisation, 19.8 million people died from cardiovascular diseases worldwide in 2022, representing about 32% of all deaths. Of these deaths, 85% were attributed to heart attacks and strokes. The above statistics reflect the global burden of the disease, not the probability of any parent developing the disease.
The WHO identifies raised blood pressure, blood glucose, and blood lipids as some of the detectable factors of increased risk of cardiovascular disease. Knowing these can give you data that can’t be derived from your energy level, body weight, or fitness. Testing at Pathology Lab can support this assessment, with results interpreted alongside your medical history.
Cholesterol: Look Beyond the Total Number
The lipid profile includes such parameters as total cholesterol, LDL cholesterol, HDL and triglycerides. LDL cholesterol is considered "bad" as it causes fat buildup in the vessels. If the total cholesterol is the only parameter analyzed, you won't be able to learn some important data that could assist you in estimating your health condition.
For people in good health without any disease, it is advised to take a cholesterol test every four to six years according to the Centers for Disease Control and Prevention. People with heart disease, diabetes and with a history of high levels of cholesterol have to check this indicator more frequently. It is basic general advice for America – your doctor will give you the more specific advice.
Any data that is not "normal" in the lab should be discussed. You should know how to analyze the results taking into account your blood pressure, smoking and other problems.
Blood Sugar: A Longer View Can Be Useful
The outcome of an A1C test is supposed to show the average blood sugar levels over 3 months. As a single glucose measurement shows the level of blood sugar at some particular moment of time, Blood Glucose Exposure Level is able to provide some additional information about the past exposure levels of the patient's blood sugar. Diagnostic ranges for those parameters are the following:
Below 5.7% – normal range
5.7% - 6.4% - pre-diabetic range
>6.5% - diabetic range
In case there are no any symptoms, the second test is necessary to confirm the diagnosis of diabetes. Other diseases, such as blood diseases, may affect the results of the HbA1C test, and should be considered when interpreting the test.
This pre-diabetic range may be a good reminder to the busy parent of discussing diet, exercise and weight loss (where appropriate). That doesn't imply that there's no possible escape route from diabetes.
When creating your tests, be sure to talk to your health care provider about what steps must be taken to resolve a certain health concern. However, additional testing of the package may result in data that is not relevant.
Blood Pressure Belongs in the Same Conversation
Nevertheless, it is important to remember that blood pressure cannot be determined through blood tests, but is crucial for the cardiovascular system and measured using a cuff. According to the American Heart Association, hypertension does not have any symptoms or indications. If the blood pressure is less than 120/80 mm Hg, one should do one visit per year.
The information that is listed at home SHOULD be used for the exam. The information collected during multiple visits would be preferable over a single visit.
Do You Also Need an ECG or Treadmill Test?
The number of tests increases; however, this doesn’t mean that you get an extra reassurance. According to the US Preventive Services Task Force (USPSTF), screening the resting or exercise ECG for the general population with no symptoms of cardiovascular disease is not recommended.
This recommendation relates to the issue of screening. If any complaints or symptoms are present, it's a completely different story.
If necessary, additional tests may be done during the cardiology consultation. These are ECG, echo and ambulatory blood pressure monitoring. These tests will be done depending on the symptoms, findings and history.
Make the Results Useful in Everyday Life
At the end of the appointment, you should ask yourself 3 questions: What should I do now? What might I do differently if I wanted to? When is it time to review it?
As stated, the recommended amount of physical activity for adults is 150 minutes of moderate-intensity physical activity per week and 2-3 days per week of muscle-strengthening activities, as suggested by WHO. Physical activity with walking or with an adapted walking regimen around the workplace could be used to introduce walking. If there are any symptoms or heart problems, consult with your healthcare provider about the activity schedule that would suit you best.
WHO also recommends limiting salt consumption, eating more fruits and vegetables and not smoking as a way of avoiding cardiovascular diseases. Pick those changes that you and your family may want to implement. Discuss with your clinician how they work for you. It may still be necessary to prescribe.
Finally, it is never an excuse to not get necessary treatment if a regular screening is done. If chest pain is accompanied by shortness of breath, sweating and pain in the arm or jaw, this should be acted upon immediately. However, blood test results may turn out to be normal, even if you have some new symptoms.
