What is Heart Failure

Heart failure, also known as congestive heart failure (CHF), is a disease state that covers any reason why the heart is not pumping blood efficiently. Click here to learn more about heart failure and heart failure research at CVRTI.

Blue Heart Image Representing Sudden Cardiac Death- CVRTI

What is Sudden Cardiac Death?

Sudden cardiac death (SCD) is a heart arrhythmia condition when the heart abruptly stops functioning, leading to a halting of breathing and consciousness, resulting in death. SCD is one of the most significant causes of natural deaths globally. Click here to learn more about sudden cardiac death at CVRTI.

What is Cardiac Arrhythmia?

The heart’s primary function is to pump blood throughout the body. This is done by an electrical connection that originates from the sinoatrial node (SA node). The electrical impulse begins at the SA node travels throughout the heart. The electrical impulse travels along a pathway through the heart to create the heart’s movement.

Blue Figure with Arms Outstretched and Bright Red Heart - CVRTI Electrophysiology

What is Electrophysiology?

We all know the feeling of our heart racing or fluttering as we get excited, nervous, or stressed. But what is going on in the heart to get a heart rhythm? The heart contracts and expands to pump blood through the body using an electrical stimulus that starts in the heart’s sinoatrial node. Click here to learn more about Electrophysiology at CVRTI.


What is Cardiogenic Shock?

Cardiogenic shock (CS) is a life-threatening condition whereby the heart can’t pump enough blood to meet the body’s needs. While a severe heart attack most often causes it, not everyone who has a heart attack experiences cardiogenic shock. While a serious heart attack usually damages the left ventricle (the main pumping chamber), it can sometimes damage the right ventricle, which pumps blood to the lungs.

Cardiac Metabolism

What is Cardiac Metabolism?

The goal of cardiac metabolism is to produce chemical energy (ATP) to fuel the heart function. By doing so, the heart is able to continuously pump oxygenated blood to the rest of the body. In normal, healthy cardiac metabolism an efficient rate of ATP fuels heart muscle function. In the context of heart failure, cardiac metabolism becomes impaired. .Click here to learn more about Cardiac Metabolism at CVRTI.

2022 Heart Disease Statistics You Need to Know

Arrhythmias, congestive heart failure, high blood pressure, cardiac arrest are all different types of heart diseases. Some of these can be controlled or prevented through diet, exercise, or medications, but some are sudden and unexpected. Some people are born with heart disease, and some develop heart disease through lifestyle choices. While there are many types and causes of heart disease, it is important to be aware of the symptoms. Below are 6 shocking heart disease statistics.Click here to learn more about Heart Disease at CVRTI.

What is Arrhythmogenic Cardiomyopathy?

Arrhythmogenic cardiomyopathy is a genetic condition that causes damage to the heart muscle and one or both ventricles. The damage replaces the heart muscle tissue with fibrosis scar tissue and fat. It is the second most common cause of death in young athletes. Click here to learn more about Arrhythmogenic Cardiomyopathy at CVRTI.

What Is An Electrocardiogram?

An electrocardiogram, also known as an EKG or ECG, is a safe, non-invasive test that helps your doctor monitor for heart disease. The test monitors the electrical activity of your heart through electrode-stickers placed on the skin of your arms, legs, and chest. Click here to learn more about Electrocardiogram at CVRTI.

What Is Heart Failure Therapy?

Cardiovascular disease resulting in heart failure is the leading cause of death for people living in developed countries. In an effort to find better ways to treat CVD, scientists have been researching a variety of heart failure therapies. Some of those are discussed in this article. Click here to learn more about Heart Failure Therapy at CVRTI.

Red Transparent Body with Heart - What Is Myocardial Recovery Graphic

What Is Myocardial Recovery?

Heart failure (HF) is characterized by a pathologic process known as “remodeling” that involves impairment of the function of the heart and progressive dilation of the chambers of the heart. The process of remodeling is associated with adverse cellular, structural, and functional myocardial changes, that had long been deemed progressive and unidirectional.

What is the Difference Between Pacemakers and Defibrillators?

The heart is the most important muscle in the body—it’s the one that keeps us alive. When the heart can’t keep up due to disease, damage, or other issues, technology is available to help. Two of the most common devices associated with heart attacks, heart disease, and other heart conditions are pacemakers and defibrillators. But what are these tools, and what makes them different? Click here to learn more about Pacemakers and Defibrillators at CVRTI.

What Effect Does Epigenetics Have on Cardiovascular Studies?

In biology, epigenetics is the study of heritable changes that do not involve alterations in the DNA sequence. The Greek prefix ‘epi’ means over, outside of, or around. Thus, the definition of epigenetics is the feature of the genetic code that exists or develops in addition to traditional genetic inheritance. Click here to learn more about Epigenetics at CVRTI.

What is Heart Failure Therapy and the Role of ACE Inhibitors, Angiotensin Receptor Blockers & Beta Blockers?

Heart disease is extremely common in the USA. Over 600,000 people die from heart disease in the United States each year, accounting for 1 in 4 causes of death. Heart disease can progress into heart failure, from which it is difficult for patients to recover normal heart function. Click here to learn more aboutHeart Failure Therapy at CVRTI.

Understanding the Stages of Cardiogenic Shock

Cardiogenic shock is an emergent condition that can damage organs, cause brain injury, or even be fatal if it isn’t recognized and treated quickly. The good news is that cardiogenic shock can be managed if it’s addressed right away. Click here to learn more about Cardiogenic Shock at CVRTI.

Human Heart on Bright Blue Background- What Are the Symptoms of Cardiogenic Shock Graphic

What Are the Symptoms of Cardiogenic Shock?

Cardiogenic shock occurs when the heart has been damaged to the point that it is no longer capable of supplying enough blood and oxygen to the body’s organs. This has the potential to be a serious medical condition that can lead to many health issues and even death. Click here to learn more about Cardiogenic Shock at CVRTI.

What Can Cause Cardiogenic Shock?

Cardiogenic shock is a serious condition that can result in death if medical attention is not sought out quickly. This condition occurs when the heart is no longer able to pump enough blood to meet the needs of your body. When there is not enough blood and oxygen making their way to the organs, it can result in organ failure and eventually death if not treated right away.

Warning Signs of Arrhythmia

When a person’s heart beats irregularly it is called cardiac arrhythmia. In some cases, the issue may be mild and only require monitoring. However, when left unchecked and untreated, there is the potential for serious health issues, including death. Therefore, you should have a good understanding of the warning signs of cardiac arrhythmia. Click here to learn more about Arrhythmia at CVRTI.

How Cardiac Arrhythmia Can Affect Your Body: Symptoms and Causes

Cardiac arrhythmia is a medical term used to denote an irregular heartbeat. Electrical signals in the body help ensure a normal, steady heartbeat. Arrhythmia occurs when those electrical signals are not working properly. Sometimes, heart arrhythmias can be harmless, but they may indicate serious and potentially life-threatening issues.

The Early Signs, Diagnosis, and Stages of Heart Failure

The term “heart failure” may sound as though your heart completely stopped working, but that’s not the case. Heart failure means that the heart is no longer capable of pumping blood as well as it should be. It is a serious long-term condition that worsens over time. When the heart doesn’t pump blood properly, your organs will not be getting the blood needed to perform. Click here to learn more about Heart Failure at CVRTI.
