Cardiovascular disease (CVD) is the leading cause of death in the US, accounting for one in every five deaths. About one person dies every 34 seconds, which cost the US $229 billion in 2018. The WHO estimates more than 17 million people die from CVD each year. CVD refers to conditions affecting the heart and blood vessels, including coronary artery disease, stroke, heart failure, and arrhythmias. Risk factors for CVD include hypertension, high cholesterol, diabetes, smoking, obesity, and physical inactivity. While some risk factors cannot be modified, such as age and genetics, lifestyle modifications and medical treatments can help manage and reduce the risk of CVD.
Identifying individuals at high risk for CVD is a critical step in reducing the burden of this disease. Early detection of CVD risk factors can help prevent or delay the onset of the disease. Screening for CVD risk factors, such as blood pressure and cholesterol levels, can identify individuals who are at increased risk for developing CVD. This article will discuss the details of cardiovascular disease, the symptoms, risk factors associated with CVD, and various approaches to preventing, managing, and treating CVD.

What is Cardiovascular Disease?
Cardiovascular disease is a term used to describe a group of conditions that affect the heart and blood vessels. These conditions can include coronary artery disease, heart failure, arrhythmias, and stroke. Coronary artery disease is the most common type of CVD and occurs when the arteries that supply blood to the heart become narrow or blocked, leading to chest pain or a heart attack. Heart failure occurs when the heart is unable to pump enough blood to meet the body's needs, leading to fatigue, shortness of breath, and swelling in the legs and feet. Arrhythmias are abnormal heart rhythms that can cause palpitations, dizziness, or fainting, and can also increase the risk of stroke. A stroke occurs when the blood supply to the brain is interrupted, either by a blockage or a bleed. Atherosclerosis is a contributing factor to CVD. This is a condition where plaque builds up in the arteries, reducing blood flow and increasing the risk of heart attack and stroke.
Symptoms of Cardiovascular Disease
Cardiovascular disease can present with a range of symptoms, which can vary depending on the type of CVD a person has. Some of the most common symptoms of CVD include chest pain, shortness of breath, fatigue, swelling in the legs and feet, and irregular heartbeat.
Chest pain, also known as angina, is a common symptom of coronary artery disease, which occurs when the arteries supplying blood to the heart become narrow or blocked. Chest pain can feel like pressure or squeezing in the chest and can also spread to the arms, neck, or back.
Shortness of breath is another common symptom of CVD, which can occur when the heart is unable to pump enough blood to meet the body's needs. Fatigue is also a common symptom of CVD, which can occur due to reduced blood flow to the muscles and organs.
Swelling in the legs and feet can also be a symptom of CVD, which can occur when the heart is unable to pump blood efficiently, causing blood to pool in the legs and feet. Irregular heartbeat, also known as arrhythmia, can also be a symptom of CVD, which can increase the risk of stroke.
It is important to note that some people with CVD may not experience any symptoms until the condition has progressed. Therefore, regular check-ups with a healthcare provider are important to monitor and manage any potential CVD risk factors.
Risk Factors for Cardiovascular Disease
Several risk factors can contribute to the development of CVD. High blood pressure, also known as hypertension, is a major risk factor for CVD, as it can cause damage to the arteries and make the heart work harder to pump blood. High cholesterol levels can lead to the accumulation of fatty deposits in the arteries, which can also increase the risk of CVD.
Smoking is a significant risk factor for CVD, as it can damage the lining of the arteries and increase the risk of atherosclerosis. Individuals with diabetes are also at increased risk of developing CVD, as high blood sugar levels can cause damage to the arteries and increase the risk of atherosclerosis.
Obesity is another risk factor for CVD, as it can lead to high blood pressure, high cholesterol levels, and type 2 diabetes. Additionally, carrying excess weight can put extra strain on the heart and increase the risk of heart failure.
Having a family history of CVD can also increase an individual's risk of developing the condition, as genetics can play a role in developing high blood pressure and heart disease.
Overall, reducing these risk factors can play a key role in preventing CVD. Lifestyle changes such as maintaining a healthy diet, engaging in regular physical activity, and quitting smoking can help reduce the risk of developing CVD. In addition, managing underlying medical conditions such as high blood pressure, high cholesterol, and diabetes can also help reduce the risk of CVD.
It is important to identify and manage any potential risk factors for CVD to prevent its development or progression. This can involve lifestyle changes such as maintaining a healthy diet, engaging in regular physical activity, quitting smoking, and managing underlying medical conditions. Regular check-ups with a healthcare provider are also important to monitor and manage any potential CVD risk factors.
What Causes Heart Disease?
Cardiovascular disease is a complex condition with different causes depending on the specific type. Atherosclerosis, a condition where plaque builds up in the arteries, is a common cause of CVD and can lead to coronary artery disease and peripheral artery disease. Atherosclerosis can be caused by a combination of factors, including high blood pressure, high cholesterol levels, smoking, and a family history of heart disease.
Genetic problems or medications can also cause heart issues such as arrhythmias, a condition where the heart beats too fast, too slow, or irregularly. Aging, infections, and rheumatic diseases are common causes of valve diseases, which occur when the valves in the heart do not function properly, leading to reduced blood flow.
The risk factors mentioned in the previous section go hand in hand with contributing to the development of CVD, including diabetes, obesity, a sedentary lifestyle, and stress. Diabetes can cause damage to the blood vessels and increase the risk of atherosclerosis, while obesity can increase blood pressure and cholesterol levels. A sedentary lifestyle and stress can also contribute to the development of CVD, increasing the risk of high blood pressure and other CVD risk factors.
Functional Medicine Labs for Heart Disease Screening
Functional medicine labs can be valuable tools in identifying and managing risk factors for CVD. Advanced lipid panels, inflammatory markers, and labs to assess for underlying conditions that can lead to CVD are some of the functional medicine labs that can be used to evaluate an individual's CVD risk.
Advanced Lipid Panels
The NMR LipoProfile can provide more detailed information about an individual's cholesterol levels beyond traditional lipid panels. These tests can assess the size and density of lipoprotein particles, providing a more accurate assessment of CVD risk.
Inflammatory Markers
High-sensitivity C-reactive protein (hs-CRP) can provide information about the level of inflammation in the body, which can contribute to the development of atherosclerosis and other types of CVD. Elevated levels of these markers can indicate an increased risk of CVD.
Markers of Oxidative Stress
Oxidized LDL can indicate the level of damage to cells and tissues in the body caused by free radicals. Increased levels of these markers can be associated with an increased risk of CVD and other chronic conditions.
Lifestyle Panel
This exceptional test assesses cardiac risk by testing multiple indicators of heart health, including a basic lipid profile and a (hs-CRP). The panel also includes two unique tests, the HDL Map and the Cholesterol Balance. With the information obtained from the Lifestyle Panel, healthcare providers can determine a patient's individual cardiac risk and gain insight into appropriate treatment regimens.
Diabetes Panel
People with diabetes have an increased risk of heart disease. This Diabetes Panel offers various tests to evaluate glucose metabolism, such as fasting insulin, fasting glucose, and hemoglobin A1c.
Omega Panel
Higher levels of omega-3 fatty acids are associated with fewer cardiovascular problems. The red blood cell omega-3 & 6 blood test is a valuable tool to determine levels and provide personalized advice about increasing omega-3 intake through diet or supplementation.
TMAO
TMAO is a byproduct generated by gut bacteria when consuming certain animal foods. It has been linked to an increased risk of heart disease. TMAO levels can be determined with a blood test, and individualized dietary advice can be provided.
Comprehensive Metabolic Panel (CMP)
For individuals at risk of arrhythmia or experiencing palpitations or unusual heart rhythms, evaluating electrolytes such as sodium, potassium, and calcium is important, and a CMP will provide that information.
Thyroid Panel
Thyroid dysfunction can also be associated with heart conditions, including arrhythmias. A comprehensive thyroid panel can provide a comprehensive overview of how the thyroid is functioning, allowing for appropriate intervention if necessary.
MTHFR
MTHFR is an enzyme responsible for converting homocysteine. Elevated homocysteine levels can be associated with an increased risk of CVD. Assessing if there is a gene variant that doesn't allow for the conversion of homocysteine back into methionine or cysteine can be helpful for assessing CVD risks.
Overall, functional medicine labs can provide a more comprehensive assessment of an individual's CVD risk beyond traditional screening methods. By identifying potential risk factors early, healthcare providers can develop personalized treatment plans to manage or prevent CVD. It is important to discuss the use of functional medicine labs with a healthcare provider to determine the most appropriate tests for individual needs and circumstances.
Conventional Treatment for Heart Disease
Treatment for CVD may include medications to lower blood pressure and cholesterol, procedures such as angioplasty or bypass surgery to restore blood flow to the heart, and lifestyle changes such as quitting smoking and increasing physical activity.
CVD can have serious and sometimes life-threatening consequences, but treatment options are available to help manage symptoms and reduce the risk of complications. Treatment for CVD is often multifaceted and may involve a combination of medications, procedures, and lifestyle changes.
Medications are commonly used to manage CVD. Blood pressure-lowering medications such as ACE inhibitors, beta-blockers, and calcium channel blockers can help reduce the workload on the heart and lower the risk of complications. Cholesterol-lowering medications such as statins can help reduce the amount of plaque buildup in the arteries, reducing the risk of heart attack and stroke.
Procedures such as angioplasty or bypass surgery may be necessary to restore blood flow to the heart in severe coronary artery disease cases. During angioplasty, a small balloon is inflated inside the blocked artery to widen it and improve blood flow. Bypass surgery involves using a healthy blood vessel from another part of the body to create a new route for blood flow around the blocked artery.
Functional Medicine Treatment for Cardiovascular Disease
Functional medicine is an integrative approach to healthcare that addresses the root causes of disease rather than just treating symptoms. When it comes to CVD, functional medicine can offer a variety of treatments that address the underlying factors contributing to the development of the condition.
Prevention is a key factor in functional medicine approaches to CVD. It involves adopting a healthy lifestyle, including eating a balanced diet, exercising regularly, maintaining a healthy weight, not smoking, and managing any underlying medical conditions such as high blood pressure or diabetes.
One approach used in functional medicine is targeted nutrient therapy, which involves using specific vitamins, minerals, and other nutrients to support cardiovascular health. For example, omega-3 fatty acids have been shown to reduce inflammation and lower the risk of heart disease. A more detailed discussion will be provided in the next sections. These interventions can help reduce the risk of developing CVD and improve outcomes for those already living with the condition.
It is important to note that functional medicine approaches to CVD should be a consideration in conjunction with conventional medical treatments, as cardiovascular disease can have serious and sometimes life-threatening consequences. Working with a healthcare provider who is knowledgeable in both conventional and functional medicine can help individuals with CVD develop a comprehensive and personalized treatment plan.
Heart Healthy Diet
A heart-healthy diet is an important aspect of managing and preventing cardiovascular disease. The right diet can help control high blood pressure, high cholesterol, and obesity – all major risk factors for CVD.
A heart-healthy diet typically focuses on whole, unprocessed foods, particularly fruits, vegetables, whole grains, lean proteins, and healthy fats. Foods high in saturated and trans fats, added sugars, and salt should be limited.
One nutritional way to improve heart health is to eat foods that help to lower cholesterol. They include more soluble fiber in the diet, as it can help reduce LDL ("bad") cholesterol levels. Another way is to consume more plant-based proteins, such as legumes, nuts, and seeds, instead of animal-based proteins like red meat. Plant-based proteins are typically lower in saturated fat and cholesterol and can help improve overall heart health.
Research has shown that following a Mediterranean diet can improve several risk factors for heart disease, including high blood pressure, high cholesterol levels, and obesity. This diet is rich in fiber, vitamins, and minerals and low in saturated and trans fats, which can help reduce inflammation, improve blood vessel function, and lower the risk of heart disease. The Mediterranean diet is a heart-healthy eating pattern that is based on the traditional foods and cooking styles of the countries bordering the Mediterranean Sea. This diet emphasizes plant-based foods, such as fruits, vegetables, whole grains, legumes, nuts, fish, and healthy fats like olive oil.
Another specific diet that is good for heart health is the DASH (Dietary Approaches to Stop Hypertension) diet. This diet is a heart-healthy eating pattern that is rich in fruits, vegetables, whole grains, low-fat dairy products, lean proteins, and healthy fats. This diet is designed to help lower blood pressure and reduce the risk of heart disease. The DASH diet is a balanced and nutritious way to support heart health, and it emphasizes whole foods that are naturally low in sodium and high in important nutrients.
Other nutrition ways for a heart-healthy diet include limiting alcohol intake, choosing healthy cooking methods (such as grilling, broiling, or baking instead of frying), and incorporating more heart-healthy fats (such as those found in fatty fish, nuts, and avocados).
Overall, a heart-healthy diet can help reduce the risk of coronary artery disease and other cardiovascular conditions. Consultation with a healthcare provider, functional medicine practitioner, or a registered dietitian can provide individualized guidance on developing and maintaining a heart-healthy diet.
Supplements for Heart Health
Supplements can be a valuable addition to a heart-healthy lifestyle, but they should be used with caution and under the guidance of a healthcare provider. Some supplements that may benefit heart health include:
Omega-3 Fatty Acids
Found in fatty fish, flaxseeds, and chia seeds, omega-3 fatty acids can help reduce inflammation, lower triglycerides, and improve overall heart health.
Coenzyme Q10 (CoQ10)
This antioxidant is involved in energy production in the body and may help improve heart function and reduce the risk of heart failure.
Magnesium
This mineral is involved in many bodily functions, including heart health. Studies have shown that magnesium supplementation may help reduce blood pressure and improve heart function.
Vitamin D
This important nutrient is involved in bone health but may also play a role in heart health. Low vitamin D levels have been associated with an increased risk of heart conditions.
Garlic
This pungent herb has been shown to have blood pressure-lowering effects and may help reduce the risk of heart disease.
Hawthorn
This herb has been traditionally used for heart health and may help improve blood flow and reduce high blood pressure.
Berberine
This compound is found in several plants, including goldenseal and barberry, and has been shown in some studies to have potential benefits for heart health. It has been shown to help lower cholesterol levels, reduce blood pressure, and improve insulin sensitivity.
Fiber
Fiber is an important nutrient that can help improve heart health by reducing the amount of cholesterol absorbed from food. It is naturally found in fruits, grains, vegetables, and legumes, and it is recommended to consume at least 25 to 30 grams of fiber daily. Men under the age of 51 should aim for 38 grams a day. While it is best to get your daily dose from your diet, fiber supplements can be another option.
Sterols and Stanols
These plant compounds can help reduce cholesterol absorption in the gut. They are structurally similar to cholesterol, allowing them to block cholesterol absorption in the intestines. Foods that are naturally rich in sterols and stanols include nuts, seeds, and whole grains. However, it can be difficult to get enough of these compounds from food alone, which is why supplements are often recommended. Consuming 2 grams of sterols and stanols daily can help lower LDL cholesterol by 8-10%. It's important to note that sterols and stanols do not affect HDL or triglyceride levels. Additionally, people who are already taking cholesterol-lowering medication should speak with their healthcare provider before adding sterol or stanol supplements to their regimen, as there may be interactions.
Red Yeast Rice
This supplement has been used in Traditional Chinese Medicine (TCM) for centuries. It is made by fermenting rice with a type of yeast called Monascus purpureus. This fermentation process produces a compound called monacolin K, which is similar in chemical structure to the active ingredient in some cholesterol-lowering drugs. Some studies have suggested that red yeast rice may help lower total cholesterol, triglycerides, and LDL cholesterol levels in people with high cholesterol. However, the evidence is still mixed about this supplement.
While supplements can be helpful for some people, they are not a substitute for a healthy diet and lifestyle. It's important to work with a healthcare provider to determine the appropriate supplements and dosages for your individual needs. Additionally, it's important to be aware that some supplements may interact with prescription medications, so it's important to disclose all supplements you take to your healthcare provider.

Complementary and Alternative Medicine for Cardiovascular Health
Complementary and Alternative Medicine (CAM) approaches can also play a role in promoting heart health. Lifestyle changes are an important approach in CAM and are also a vital part of managing CVD. Quitting smoking is one of the most important steps a person can take to reduce their risk of complications. Physical activity is also important for managing CVD, as it can help improve circulation and reduce the workload on the heart. Other CAM approaches for CVD may include acupuncture, herbal medicine (herbal supplements mentioned in the previous section), and mind-body therapies like meditation and yoga.
Acupuncture, an ancient Chinese therapy, involves the insertion of fine needles at specific points on the body to promote healing and reduce pain. Several studies have shown that acupuncture may effectively reduce blood pressure, a major risk factor for CVD.
Mind-body therapies like meditation and yoga can also effectively reduce stress and promote relaxation, which can improve cardiovascular health. Meditation has been shown to lower blood pressure and reduces stress hormones, while yoga can improve heart health by reducing stress and improving circulation.
While CAM approaches can be used in conjunction with conventional medical treatments to support heart health. It's important to speak with a healthcare provider before trying any new CAM therapies to ensure they are safe and effective for your specific needs. These approaches can help improve overall health and reduce stress, which can, in turn, support cardiovascular health.
Summary
Cardiovascular disease is a group of conditions that affect the heart and blood vessels and is a major cause of disability and death worldwide. It can be prevented by adopting a healthy lifestyle and managing underlying medical conditions, and can be treated through a combination of medications, procedures, and lifestyle changes. The most common types of CVD include coronary artery disease, heart failure, arrhythmias, and stroke. While atherosclerosis contributes, treatment options are available to manage CVD, including medications and procedures to restore blood flow and lifestyle changes. Treatment for CVD is often multifaceted and may involve medications, procedures, and lifestyle changes. It is important for individuals with CVD to work closely with their healthcare providers to develop a personalized treatment plan that meets their individual needs and circumstances. By taking steps to manage CVD, individuals can improve their quality of life and reduce their risk of complications.
