Our biological hearts are failing us. The heart is simply a pump. Nothing more; nothing less. However, that little pump in our chest is not a product of smart design, advanced mechanical engineering, and manufacturing. Instead, our biological hearts are products of random evolution and blind non-artificial selection.
Our biological hearts are limiting our lifespan on Earth. If you are content with the idea of having a heart that lasts about 80 years in average, good for you. There is no need to read any further. You can go back to Tik Tok. However, if you want more, if you would rather live a longer and healthier life, keep reading.
Cardiovascular diseases (CVDs)
CVDs are the leading cause of death worldwide. These diseases affect the heart and blood vessels and include conditions such as coronary artery disease, heart failure, stroke, and hypertension (high blood pressure). CVDs have a substantial impact on public health, healthcare systems, and economies globally.
CVDs kill about 20 million humans each year around the world. In the United States, one human dies of CVD approximately every 30 seconds. CVDs encompass a wide range of conditions that affect the heart and blood vessels. Some of the most common CVDs include coronary artery disease (leading to heart attacks), stroke, heart failure, arrhythmias (abnormal heart rhythms), and hypertension (high blood pressure).
Certain risk factors increase the likelihood of developing CVDs. These include smoking, unhealthy diet, physical inactivity, excessive alcohol consumption, obesity, high blood pressure, high cholesterol, and diabetes. Many CVDs are preventable by addressing those risk factors through lifestyle modifications and proper medical management. Early detection and effective management of cardiovascular diseases can improve outcomes and quality of life. Regular medical check-ups, screening for risk factors, and adherence to prescribed treatments are crucial.
CVDs place a substantial economic burden on societies because it leads to costly hospitalizations, surgeries, medication use, and long-term medical management. The economic impact of CVDs is significant due to healthcare expenditures, lost productivity, and decreased quality of life. The cost of treating and managing cardiovascular diseases places strain on both individuals and society as a whole. Governments, healthcare organizations, and public health institutions work to raise awareness about cardiovascular diseases, promote heart-healthy behaviors, and implement policies and interventions to reduce risk factors and improve cardiovascular health.
Given their widespread impact and consequences, efforts to prevent and manage cardiovascular diseases are crucial for improving global health outcomes and reducing the burden on healthcare systems. Raising awareness, promoting healthy lifestyles, and ensuring access to quality medical care are important steps in combating this leading cause of death. CVDs affect people of all ages and income levels, but they disproportionately impact low- and middle-income countries where resources for prevention and treatment may be limited.
The human heart is a muscular pump circulating blood throughout the body to deliver oxygen and nutrients to cells, and to remove waste products from cells. The heart operates through a coordinated series of contractions and relaxations, known as the cardiac cycle.
Heart failure is a significant CVD that occurs when the heart is unable to pump blood effectively, leading to a range of symptoms and complications. Heart failure is a prevalent condition, affecting millions of people around the world. It is more common in older adults, but it can occur at any age.
Given the significant impact of heart failure on public health, healthcare systems, and individuals' well-being, efforts to raise awareness, promote healthy lifestyles, and advance medical treatments remain essential in reducing its burden on societies worldwide.
An artificial heart, also known as a mechanical heart or a heart assist device, is a medical device designed to temporarily or permanently replace the function of a damaged or failing human heart. Currently, artificial hearts are only used as a treatment option for individuals with severe heart conditions that cannot be managed effectively through medication or other interventions.

The Human Heart
The human heart is a muscular pump circulating blood throughout the body to deliver oxygen and nutrients to cells, and to remove waste products from cells. The heart operates through a coordinated series of contractions and relaxations, known as the cardiac cycle.
The heart is divided into four chambers: two atria (upper chambers) and two ventricles (lower chambers). The left side deals with the systemic circuit delivering oxygenated blood to body tissues. The right side of the heart deals with the pulmonary circuit sending deoxygenated blood to the lungs to pick up oxygen and to release carbon dioxide.
The heart has four valves that ensure one-way blood flow. The atrioventricular valves (tricuspid and mitral) separate the atria from the ventricles, and the semilunar valves (pulmonary and aortic) separate the ventricles from the arteries.
The cardiac cycle followed by the heart includes four main phases:
a. Diastole relaxation when blood flows into the atria from the body and lungs.
b. Atrial contraction when the atria contracts, pushing blood into the ventricles through the atrioventricular (AV) valves (tricuspid on the right and mitral on the left).
c. Ventricular contraction (Systole) when ventricles contract, closing the AV valves to prevent backflow into the atria. The pulmonary and aortic valves (semilunar valves) open, allowing blood to be pumped into the pulmonary artery and aorta, respectively.
d. Ejection when deoxygenated blood from the right ventricle is sent to the lungs to pick up oxygen, and oxygenated blood from the left ventricle is pumped into the body's arteries to supply oxygen to tissues.
The heart's contractions are coordinated by an electrical conduction system. The sinoatrial (SA) node, located in the right atrium, initiates electrical impulses that cause atrial contraction. The impulses then travel to the atrioventricular (AV) node, which delays the signal to allow the ventricles to fill. From the AV node, the impulse travels through the bundle of His and the Purkinje fibers, causing ventricular contraction.

The impulses then travel to the atrioventricular (AV) node, which delays the signal to allow the ventricles to fill. From the AV node, the impulse travels through the bundle of His and the Purkinje fibers, causing ventricular contraction.
The heart beats rhythmically due to the inherent electrical activity of cardiac cells. The SA node acts as the heart's natural pacemaker, setting the pace for the heartbeat. The continuous coordination of contraction and relaxation ensures that blood is efficiently pumped to all parts of the body, supplying oxygen and nutrients and removing waste products. Any disruption in this complex process can lead to heart-related issues and disorders.
Heart Failure
Heart failure is a significant CVD that occurs when the heart is unable to pump blood effectively, leading to a range of symptoms and complications. Heart failure is a prevalent condition, affecting millions of people around the world. It is more common in older adults, but it can occur at any age.
Heart failure is a leading cause of morbidity (illness) and mortality (death) globally. It contributes to a substantial number of hospitalizations and accounts for a significant portion of cardiovascular-related deaths. Heart failure can be caused by various underlying conditions that affect the heart's structure or function. These conditions include coronary artery disease (blocked or narrowed blood vessels), hypertension (high blood pressure), heart valve disorders, cardiomyopathy (weakened heart muscle), and congenital heart defects.
Symptoms of heart failure can include shortness of breath, fatigue, swelling in the legs and ankles (edema), rapid or irregular heartbeat, and difficulty with physical activities. Complications of heart failure can include fluid buildup in the lungs (pulmonary edema), kidney dysfunction, arrhythmias (abnormal heart rhythms), and increased risk of blood clots.
Many cases of heart failure can be prevented by addressing risk factors such as smoking, high blood pressure, high cholesterol, diabetes, and maintaining a healthy lifestyle that includes regular exercise and a balanced diet. Lifestyle modifications, medications, medical devices (such as pacemakers or implantable defibrillators), and, in severe cases, heart transplantation or mechanical circulatory support (like ventricular assist devices) are among the treatment approaches.

Artificial Hearts
An artificial heart, also known as a mechanical heart or a heart assist device, is a medical device designed to temporarily or permanently replace the function of a damaged or failing human heart. Currently, artificial hearts are only used as a treatment option for individuals with severe heart conditions that cannot be managed effectively through medication or other interventions.
An artificial heart serves the primary function of pumping blood throughout the body, replicating the vital role of the natural heart. It helps maintain circulation and supplies oxygen and nutrients to tissues while removing waste products.
Artificial hearts can be used in both temporary and permanent scenarios. Temporary use might involve providing support to a patient while they await a heart transplant. Permanent use might be considered when a patient is not eligible for a heart transplant due to various reasons.
Types of Artificial Hearts:
Artificial hearts can be used in both temporary and permanent scenarios. Temporary use might involve providing support to a patient while they await a heart transplant. Permanent use might be considered when a patient is not eligible for a heart transplant due to various reasons.
Types of Artificial Hearts:
a. Total Artificial Heart (TAH): A TAH is a device that replaces both the left and right ventricles of the natural heart. This would be used in cases of end-stage heart failure when both sides of the heart are severely compromised.
b. Ventricular Assist Device (VAD): A VAD is a device that assists one or both ventricles of the heart. This could be used as a bridge to transplantation, allowing patients to regain some level of normal activity while awaiting a donor heart.
c. Biventricular Assist Device (BiVAD): This device assists both the left and right ventricles and can be used as a bridge to transplant or for long-term support in cases of severe heart failure.
The implantation of an artificial heart requires surgical intervention. The device is connected to the patient's circulatory system, typically through the aorta and pulmonary artery. External power sources and control units are used to regulate the device's pumping mechanism. Artificial hearts require an external power source to operate. This can involve an electrical connection to an external console or a wearable battery pack that patients carry with them.
Implanting and managing an artificial heart comes with challenges and risks, including infection, blood clot formation, bleeding, device malfunction, and the need for lifelong medical supervision. Over the years, advancements in medical technology have led to improvements in the design, durability, and functionality of artificial hearts. Researchers continue to work on developing more sophisticated devices with longer lifespans and fewer complications.
Artificial hearts have the potential to significantly improve the lives of individuals with severe heart conditions by providing them with a functional circulatory system. However, they are complex medical interventions that require careful assessment, specialized medical care, and ongoing monitoring.

The Artificial Era
Let's be honest. Once humanity develops safe artificial organs that can function better than biological ones, will you pass on the opportunity to protect and expand your life? No one knows if life has a purpose or not. Idea entrepreneurs sell you different versions. Some sell you the concept that life on Earth is controlled by supernatural forces, and that the journey through spacetime is some sort of training or boot camp for an afterlife. Suffering on Earth can get you rewards that you redeem in an afterlife. Others sell you the notion that since you only live once, your purpose is to enjoy a hedonistic pleasure-seeking journey. There are many ideas for sale in the marketplace. It's up to you to decide what you want to buy into.
All things being equal, chances are that given the choice most people will opt for longer and better lives than the opposite alternative of shorter and worse lives. Once artificial organs become available, most people will consider upgrading their biological organs produced by non-artificial evolution to artificial ones produced by artificial design and manufacturing.
The Artificial Era is beginning. Everything artificial (i.e. created by humans) is 100% natural because humans are part of nature. However, not everything natural is artificial. Humans are beginning to realize that artificial solutions are often superior and preferable to non-artificial ones. Just like people switched from horses to cars, and from messenger pigeons to cellphones, people will gradually shift from biological organs to artificial ones. AI will help us get there. You bet.
