Cardiovascular Screening Guide: Which Heart Tests Are Included?

Cardiovascular screening is one of the most important steps you can take toward understanding your heart disease risk. In the UK, cardiovascular disease remains a leading cause of mortality, yet many risk factors can be identified early through routine blood-based testing. Whether you live in London or elsewhere in the UK, knowing which heart tests are included in a cardiovascular screening — and what each biomarker may reveal — can help you make more informed decisions about your wellbeing.

What Is Cardiovascular Screening?

Cardiovascular screening refers to a series of blood-based tests and health assessments designed to evaluate your risk of developing heart and circulatory conditions. It typically measures biomarkers associated with cholesterol levels, blood sugar regulation, inflammation, and organ function — all of which can indicate how well your cardiovascular system is performing.

Unlike diagnostic procedures carried out in hospital settings, preventive cardiovascular screening focuses on identifying potential risk indicators through accessible, nurse-led blood testing and reporting.

Which Heart Tests Are Typically Included in Cardiovascular Screening?

The specific tests included in a cardiovascular screening package can vary between providers. However, most comprehensive heart health panels include a combination of the following blood-based biomarkers and clinical measurements.

Lipid Profile (Cholesterol Panel)

A lipid profile is the cornerstone of any cardiovascular screening. It measures the fats circulating in your bloodstream and typically includes:

• Total Cholesterol — The overall amount of cholesterol in your blood
• LDL Cholesterol — Often referred to as “bad” cholesterol; elevated levels may contribute to plaque build-up in the arteries
• HDL Cholesterol — Sometimes called “good” cholesterol; higher levels can suggest a protective effect on the cardiovascular system
• Triglycerides — A type of fat linked to dietary intake and metabolic health; raised levels may indicate increased cardiovascular risk
• Total Cholesterol/HDL Ratio — A calculated ratio that can provide a clearer picture of relative heart disease risk

Blood Glucose and HbA1c

Blood sugar regulation is closely linked to cardiovascular health. Diabetes and pre-diabetes are well-established risk factors for heart disease, making glucose testing an essential component of heart screening.

• Fasting Blood Glucose — Measures your blood sugar level after a period of fasting; elevated results may suggest impaired glucose metabolism
• HbA1c (Glycated Haemoglobin) — Reflects your average blood sugar levels over the preceding 8–12 weeks, offering a longer-term view of glucose control

Inflammatory Markers

Chronic low-grade inflammation is increasingly recognised as a contributing factor in cardiovascular disease development.

• High-Sensitivity C-Reactive Protein (hs-CRP) — An inflammatory marker that, when persistently elevated, may suggest increased cardiovascular risk

Kidney Function Markers

Your kidneys and cardiovascular system are closely interconnected. Impaired kidney function can sometimes be an early indicator of vascular changes.

• Creatinine — A waste product filtered by the kidneys; elevated levels can suggest reduced kidney efficiency
• eGFR — A calculated measure of how effectively your kidneys are filtering blood
• Urea — Another marker of kidney function that may provide additional context

Liver Function Tests

The liver plays a significant role in cholesterol metabolism and overall metabolic health.

• ALT and AST — Liver enzymes that, when elevated, may sometimes indicate metabolic stress
• GGT — Can be raised in response to alcohol intake, medication, or fatty liver changes, all of which may have cardiovascular implications

Full Blood Count (FBC)

A full blood count provides a broad overview of your general health and can highlight anaemia, infection, or other conditions that may affect cardiovascular function.

Blood Pressure and BMI

While not blood tests, most cardiovascular screening appointments include blood pressure measurement and Body Mass Index (BMI) calculation, both of which are fundamental cardiovascular risk indicators.

Who Should Consider Cardiovascular Screening?

Cardiovascular screening can be relevant for a wide range of adults, not only those who already have symptoms. You may wish to consider heart health testing if you:

• Are aged 40 or over and have not had a recent heart risk assessment
• Have a family history of heart disease, stroke, or high cholesterol
• Lead a sedentary lifestyle or have a high-stress occupation — read more about screening for lifestyle disease prevention
• Are overweight or have a BMI above the recommended range
• Smoke or have a history of smoking
• Have previously been told your cholesterol or blood pressure was borderline
• Have diabetes, pre-diabetes, or a family history of diabetes
• Simply want a baseline understanding of your cardiovascular health

How Often Should You Have Cardiovascular Screening?

There is no single answer that applies to everyone. The appropriate frequency of cardiovascular screening depends on your age, risk profile, family history, and any previous results. As a general guide:

• Low risk, no previous concerns — Every 1–2 years from age 40 onwards
• Moderate risk or family history — Annually, or as recommended by a healthcare professional
• Previously elevated results — More frequent monitoring may be advisable — discuss this with your healthcare provider

What Do Cardiovascular Screening Results Mean?

Normal Results

If your results fall within the expected reference ranges, this generally suggests that the measured biomarkers are not currently indicating elevated cardiovascular risk. It is still valuable to keep these results as a baseline for future comparison.

Borderline Results

Some results may fall just outside the optimal range. Borderline cholesterol, slightly elevated blood sugar, or mildly raised blood pressure do not necessarily mean you have a cardiovascular condition. They may indicate that lifestyle adjustments — such as dietary changes, increased physical activity, or stress management — could be beneficial.

Elevated or Abnormal Results

If one or more markers are significantly outside the reference range, your results report will typically recommend that you seek further evaluation from an appropriate healthcare professional.

Taking a Proactive Approach to Your Heart Health

Understanding your cardiovascular risk factors through regular screening is one of the most empowering steps you can take for your long-term wellbeing. Blood-based heart tests offer measurable, objective insights into key biomarkers — from cholesterol and blood sugar to inflammation and organ function — that can help you and your healthcare provider make informed decisions together.

If you have been thinking about checking your heart health, there is no need to wait for symptoms to appear. Proactive cardiovascular screening is a straightforward, accessible process that can provide valuable peace of mind.
