Screening for Heart Health: Key Tests You Should Know

Heart disease remains one of the leading causes of death in the United States, accounting for a third of all deaths nationwide. Unfortunately, many contributing factors to heart disease develop quietly over time, without any apparent symptoms. That's why regular screening for heart health is so vital.

Advanced heart screenings can now go beyond routine cholesterol checks to include imaging and biomarkers that detect subtle, early risk indicators.

Learn the purpose behind each heart health test, what it measures, and how often it's recommended based on your unique health profile. This understanding can empower you to take proactive steps toward long-term cardiovascular wellness.

One of the scariest things about heart disease is that it often progresses silently. Many of the serious risk factors develop quietly, without noticeable symptoms.

Symptoms include:

• High cholesterol
• High blood pressure
• Early plaque buildup
• Insulin resistance
• Chronic inflammation

Due to this stealthy progression, you can feel at the top of your game while your risk for heart attack, stroke, or heart disease steadily increases over time. Routine tests for heart health help uncover these hidden changes and track trends over time, giving you and your physician an early warning system. With this insight, you can take proactive steps to protect your heart.

Understanding potential threats to your cardiac health begins with a comprehensive heart checkup. A large-scale study of more than 95,000 MDVIP patients, conducted with Cleveland HeartLab, revealed the frequency of underestimating cardiovascular risks.

Basic lipid panels, commonly performed during a routine physical with a traditional primary care doctor, only identified risk in approximately 30% of patients. A multimarker approach more than doubled these findings, detecting elevated risk in 70% of patients in the study.

This research underscores that many individuals with normal cholesterol levels may still face significant threats to their heart health. A thorough heart health checkup, combining advanced bloodwork with imaging, can reveal issues early and support proactive prevention.

The foundation of a comprehensive checkup is tracking your blood and heart rate for any readings that might suggest an underlying issue. Normal blood pressure is 120/80 or less. If you consistently get readings over these numbers, you may be at risk for hypertension.

Likewise, a normal resting heart rate is between 60 and 100 beats per minute). While your heart rate may vary due to your age, health issues, and levels of activity, any consistently high, low, or irregular readings may indicate an arrhythmia.

By pairing your findings from regular office visits and home checks, you can gain a more complete and consistent view of your heart's health over time, enabling you and your physician to catch subtle changes early.

Also known as a cholesterol test, the blood lipid panel measures the fats in your blood to help assess your risk for heart disease. It evaluates four key components:

• LDL cholesterol: Often called "bad cholesterol," LDL contributes to atherosclerosis (plaque buildup in your arteries).
• HDL cholesterol: Referred to as "good cholesterol," HDL helps carry LDL away from the arteries.
• Total cholesterol: This is the sum of all cholesterol in your bloodstream.
• Triglycerides: This is a type of fat stored from excess calories; elevated levels can indicate increased heart health risks.

Advanced options, such as LDL particle number (LDL-P) and apolipoprotein B (ApoB) testing, provide a more refined picture of heart disease risk than a standard lipid panel. These tests evaluate the number and size of LDL particles circulating in the blood.

LDL-P and ApoB are essential tests because even when your LDL levels appear normal, a high concentration of small, dense LDL particles can still slip into artery walls and spark plaque formation. By uncovering often overlooked vulnerabilities, advanced lipid testing enables more personalized and effective prevention strategies.

A standard CRP test indicates inflammation in the body by testing for C-reactive protein, which is produced by the liver. The hs-CRP test is more sensitive and can measure subtle increases in CRP:

• <1 mg/L = low risk
• 1-3 mg/L = moderate risk
• >3 mg/L = high risk

Elevated hs-CRP levels can signal inflammation in the arteries and are linked to a higher risk of coronary artery disease, heart attack, or stroke.

Monitoring your fasting glucose (current sugar levels) and A1C (average blood sugar over several months) reveals how well your body manages blood sugar. Poor glucose control over time damages blood vessels, promotes inflammation, and significantly increases the risk of cardiovascular disease, even if you are not diabetic or pre-diabetic.

Beyond lifestyle habits and routine tests, a heart health check may include more advanced diagnostic tools to uncover risks that aren't immediately apparent. Specialized testing, such as CAC scoring, ECGs, ultrasounds, and the ankle-brachial index, offers a more comprehensive picture of cardiovascular health.

These evaluations are particularly valuable for those with a moderate to high risk of heart-health issues, a family history of cardiovascular events, or less obvious heart disease risks like gum disease or sleep apnea. Their results can reveal early signs of damage that standard screenings may miss.

A CAC scan measures calcium buildup in the coronary arteries. This calcium, part of plaque buildup, can narrow arteries and raise the risk of heart attacks or strokes.

The scan provides a clear view of plaque buildup and generates a score that reflects your total calcium burden. A score of 0 indicates a low risk score with no visible plaque. In comparison, higher scores reflect more plaque buildup and a greater need for closer management.

This test is typically recommended for adults 40 and over with intermediate risk, or those with unclear results from other tests. Based on your results and other risk factors, you may be asked to repeat the CAC test every 3–7 years.

An ECG captures the electrical signals that control your heartbeat, offering a clear view of your heart's rhythm and function. These signals are what allow your heart to contract and pump blood in a steady, synchronized way. When this electrical system malfunctions, it can lead to arrhythmias, inefficient blood flow, or even cardiac arrest.

In addition to detecting irregular rhythms, an ECG can also identify past heart attacks or blocked arteries. Your doctor may recommend one if you have symptoms such as chest pain, skipped beats, shortness of breath, or other risk factors.

An echocardiogram uses ultrasound to create moving images of your heart, showing how well it pumps blood and how effectively its valves function. It can detect conditions like:

• Cardiomyopathy
• Valve disease
• Blood clots
• Tumors
• Inflammation

When combined with a stress test, either with exercise or medication, your provider can also see how well your heart performs under exertion. These tests are often recommended if you have unexplained shortness of breath, chest discomfort, or other signs of heart dysfunction.

These non-invasive ultrasounds use sound waves to detect plaque buildup or narrowing in major arteries, such as the carotid arteries in the neck or the abdominal aorta. Identifying early blockages via ultrasound is an additional tool for assessing your overall stroke or aneurysm risk, providing valuable insight into your overall cardiovascular health.

The ABI test provides a quick yet sophisticated method to evaluate your circulation. Using a standard blood pressure cuff and a handheld Doppler ultrasound device, this exam compares blood pressure readings in your ankle and arm. The results can uncover early signs of peripheral artery disease (PAD), a telling predictor of poor cardiovascular health.

It's recommended for people over 65, or over 50 if there is a history of diabetes or smoking. You may also be prescribed the ABI test if you experience leg pain during physical activity. Even if you feel well, this test can reveal early issues and help guide preventive care.

A comprehensive cardiac health screening doesn't look the same for everyone. Your doctor will consider your age, sex, medical history, family history, and overall risk factors. Their recommendations may evolve as those criteria change.

For low-risk adults, a baseline panel consisting of blood pressure, lipid panels, glucose levels, and a basic EKG performed every three to five years is generally sufficient to monitor heart health. As risks and age increase, so does the frequency and type of exam. For example, an elevated risk may indicate the need for screenings every two years, accompanied by a CAC score or an ABI test. You should discuss this with your doctor.

Heart health evaluations also often intersect with sex-specific preventative care. Women's health screenings may dictate starting cholesterol tests as early as age 20 if they have diabetes or hypertension. Men's health screenings often require more frequent lipid profiling after the age of 40.

Whether you're tracking early risk or monitoring an existing condition, your heart health screening plan should always be personalized.

Screening for heart health is a wise investment in your long-term well-being. For those who value proactive, personalized care, early testing offers clarity and control. Preventive care identifies cardiac risks before they become health events.

These tests can be a powerful tool for reducing disease burden, fostering peace of mind, and helping you stay ahead of heart-related issues before they escalate. Concerns include the chance of false positives and the costs of tests, but these are generally outweighed by the benefits of early detection.

Preparing for a cardiac health screening may start a few days before your visit. To ensure accuracy, follow any instructions regarding fasting. Some tests may require you to fast for up to 72 hours.

On the day of your appointment, avoid caffeine, nicotine, and strenuous exercise unless your physician advises otherwise because these can temporarily raise your heart rate and blood pressure. You should also bring an up-to-date list of medications and supplements, including doses.

Tracking your sleep, diet, exercise, and home readings of heart rate and blood pressure can provide helpful context for your checkup's results. For example, consistently poor sleep can cause hypertension.

These insights can help your doctor interpret your results more precisely to tailor a prevention plan just for you.
