HEART DISEASE

Coquilla, D. September 2023

Heart disease, also known as cardiovascular disease, refers to a group of conditions that affect the heart and blood vessels. It is a leading cause of death worldwide. Heart disease can result in serious complications and significantly impact an individual’s quality of life.

 

Several target proteins play a critical role in the development and progression of heart failure. These proteins are involved in various cellular processes, including cardiac remodeling, inflammation, oxidative stress, and calcium handling. Understanding their mechanisms of action can provide insights into potential therapeutic interventions.

 

There are many different categories and subtypes of heart disease. The general list includes:

 

  1. Coronary artery disease (CAD): This is the most common type of heart disease and occurs when the blood vessels that supply the heart with oxygen and nutrients become narrowed or blocked.
  2. Heart failure: Heart failure refers to a condition in which the heart is unable to pump enough blood to meet the body’s needs. It can result from various underlying causes, such as coronary artery disease, high blood pressure, or heart muscle damage.
  3. Arrhythmias: Arrhythmias are abnormal heart rhythms that can cause the heart to beat too fast, too slow, or irregularly. They can range from harmless to life-threatening.
  4. Valvular heart disease: Valvular heart disease occurs when the heart valves, which regulate blood flow within the heart, become damaged or diseased. This can lead to valve stenosis (narrowing) or valve regurgitation (leakage).
  5. Congenital heart disease: Congenital heart disease refers to structural abnormalities of the heart that are present at birth. These abnormalities can affect the heart’s structure and function.
  6. Cardiomyopathy: Cardiomyopathy is a disease of the heart muscle that can cause the heart to become enlarged, thickened, or rigid. It can impair the heart’s ability to pump blood effectively.
  7. Myocardial infarction (heart attack): A heart attack occurs when there is a sudden blockage of blood flow to the heart, usually due to a blood clot. It can cause permanent damage to the heart muscle.

 

Heart disease can have multiple causes, including:

  1. Atherosclerosis: Atherosclerosis is the buildup of plaque (cholesterol, fat, and other substances) in the arteries, leading to narrowing and reduced blood flow. It is a primary cause of coronary artery disease.
  2. High blood pressure: Chronic high blood pressure can damage the arteries and increase the risk of heart disease.
  3. Smoking: Smoking damages the blood vessels, reduces oxygen supply to the heart, and increases the risk of atherosclerosis.
  4. Diabetes: Uncontrolled diabetes can damage blood vessels and increase the risk of heart disease.
  5. Obesity: Excess weight and obesity can contribute to the development of heart disease by increasing the risk of high blood pressure, diabetes, and high cholesterol levels.
  6. Family history: Having a family history of heart disease can increase the risk of developing the condition.
  7. Age and gender: The risk of heart disease increases with age, and men are generally at a higher risk than premenopausal women. However, the risk for women increases after menopause.

Heart disease can lead to various complications, including:

  1. Heart attack: A heart attack occurs when there is a sudden blockage of blood flow to the heart, leading to damage or death of the heart muscle.
  2. Heart failure: Heart failure can result from various heart conditions and is characterized by the heart’s inability to pump enough blood to meet the body’s needs.
  3. Arrhythmias: Heart disease can cause abnormal heart rhythms, which can lead to palpitations, fainting, or even sudden cardiac arrest.
  4. Stroke: Heart disease increases the risk of blood clots forming in the arteries, which can travel to the brain and cause a stroke.
  5. Peripheral artery disease: Reduced blood flow to the limbs can result in peripheral artery disease, causing pain, numbness, and difficulty walking.

Prevention plays a crucial role in reducing the risk of heart disease. Some preventive measures include:

  1. Adopting a healthy lifestyle: This includes maintaining a balanced diet, engaging in regular physical activity, maintaining a healthy weight, and avoiding smoking.
  2. Managing risk factors: Controlling high blood pressure, cholesterol levels, and diabetes through medication, lifestyle modifications, and regular monitoring.
  3. Regular check-ups: Regular medical check-ups can help identify and manage risk factors for heart disease.
  4. Stress management: Finding healthy ways to manage stress, such as exercise, relaxation techniques, or counseling, can help reduce the risk of heart disease.
  5. Limiting alcohol consumption: Excessive alcohol consumption can increase the risk of heart disease. It is important to drink in moderation or avoid alcohol altogether.

The research aims to tackle the problems and challenges associated with heart disease, including the high prevalence, significant morbidity and mortality rates, and the need for effective prevention strategies and treatments.

Solving the problem of heart disease is important due to its significant impact on public health and individual well-being. Heart disease is a leading cause of death worldwide and can result in serious complications, reduced quality of life, and increased healthcare costs. Developing effective prevention strategies, early detection methods, and innovative treatments can help reduce the burden of heart disease and improve outcomes for individuals at risk.

 

Heart disease involves various proteins and molecules that play a role in the development and progression of the condition. These may include proteins involved in inflammation, oxidative stress, lipid metabolism, and the regulation of blood pressure and cardiac function.

The mechanisms of heart disease can vary depending on the specific condition. However, common mechanisms include the development of atherosclerosis, which leads to the narrowing of arteries and reduced blood flow to the heart, and the impairment of cardiac function due to damage to the heart muscle or valves.

 

In certain heart conditions, such as rheumatic heart disease or some forms of cardiomyopathy, autoantibodies may be produced that target specific proteins in the heart tissue. These autoantibodies can contribute to inflammation, tissue damage, and the progression of heart disease.

 

Researchers are exploring various new methods, compounds, and molecules as potential cures for heart disease. These include:

  1. Gene therapy: Gene therapy aims to introduce healthy genes into the heart tissue to correct genetic abnormalities or enhance the heart’s function.
  2. Stem cell therapy: Stem cell therapy involves the transplantation of stem cells into the heart to promote tissue repair and regeneration.
  3. Targeted drug therapies: Researchers are developing targeted drugs that can modulate specific molecular pathways involved in heart disease, such as inflammation, oxidative stress, or lipid metabolism.
  4. Medical devices: Advances in medical devices, such as implantable cardiac devices or artificial heart valves, are improving the management and treatment of heart disease.

Existing competing drugs and newly discovered compound candidates for heart disease:

Existing drugs for heart disease include medications such as statins (to lower cholesterol), beta-blockers (to reduce blood pressure and heart rate), and antiplatelet agents (to prevent blood clot formation). These drugs aim to manage risk factors and symptoms associated with heart disease but may not provide a cure.

 

Several target proteins play a critical role in the development and progression of heart failure. These proteins are involved in various cellular processes, including cardiac remodeling, inflammation, oxidative stress, and calcium handling. Understanding their mechanisms of action and target proteins involved in heart failure is crucial for the development of novel therapeutic strategies.

Some of the mechanisms involve:

  1. mediating the nervous system
  2. regulating fluid
  3. oxidative stress and inflammation
  4. calcium handling
  5. gene expression

 

BioSyntex has filed patents for therapeutic candidates for the treatment of Alzheimer’s which addresses inflammation and high blood cholesterol.  BioSyntex is filing patents for therapeutic molecules for the treatment of cardiovascular disease involving: 

 

  • β-adrenergic receptor (β-AR), the receptors responsible for regulating the sympathetic nervous system on the heart and their downstream signaling pathways
  • RAAS which regulates blood pressure and fluid balance
  • RAAS inhibitors and ARBs because too much RAAS can cause vasoconstriction, sodium and water retention, and cardiac remodeling
  • Inhibitors of kappa B (NF-κB) and NADPH oxidase
  • Calcium-handling proteins, including sarcoplasmic reticulum calcium
  • ATPase (SERCA) and phospholamban (PLN)
  • sarcoplasmic reticulum calcium ATPase (SERCA) and phospholamban
  • (PLN), are critical for regulating intracellular calcium levels and cardiac contractility 

Therapies aimed at reducing inflammation and oxidative stress are also being explored. Anti-inflammatory agents, such as cytokine inhibitors or monoclonal antibodies targeting specific inflammatory pathways, have shown promise in preclinical and clinical studies. Antioxidant compounds, such as resveratrol and coenzyme Q10, have demonstrated potential in reducing oxidative stress and improving cardiac function in heart failure patients.
