An exploration into how Coronary Artery Disease can escalate into a heart attack.

Q1: What are the primary causes of Coronary Artery Disease?

• Lifestyle factors: Smoking, lack of exercise, unhealthy diet, and excessive alcohol intake.
• Health conditions: High blood pressure, high cholesterol, diabetes, and obesity.
• Genetic predisposition: Family history of heart disease.
• Age and Gender: Risk increases with age and is higher in men and post-menopausal women.

Q2: What are the typical symptoms of Coronary Artery Disease?

• Chest pain or angina: Often described as a feeling of pressure, tightness or squeezing in the chest.
• Shortness of breath: Occurs when the heart cannot pump enough blood to meet the body’s needs.
• Heart palpitations: Irregular heartbeats.
• Fatigue: Feeling unusually tired all the time.
• Nausea: A less common symptom, often overlooked.

• Smoking: 30%
• High cholesterol: 25%
• High blood pressure: 20%
• Diabetes: 10%
• Obesity: 10%
• Other Factors: 5%

Q3: How does Coronary Artery Disease lead to a heart attack?

Coronary Artery Disease develops due to the buildup of plaque in the coronary arteries, which supply oxygen-rich blood to the heart muscle. This buildup narrows the arteries, reducing blood flow to the heart. Eventually, a plaque can rupture, causing a blood clot to form. This clot can completely block the flow of blood through the coronary artery, leading to a heart attack where the heart muscle begins to die.

Coronary Artery Disease (CAD), commonly known as heart disease, is primarily caused by the buildup of plaque in the coronary arteries, which supply oxygen-rich blood to the heart muscle. This process, known as atherosclerosis, narrows the arteries and reduces blood flow to the heart. Over time, these plaques can harden or rupture, leading to the formation of a blood clot that may further block the flow of blood.

Symptoms of CAD can vary but typically include chest pain (angina), shortness of breath, fatigue, and in more severe cases, palpitations or even fainting. The severity of these symptoms can often increase with activities like exercise or emotional stress. When the blood flow becomes severely restricted or completely blocked, it can lead to a heart attack, medically known as a myocardial infarction. This acute event occurs when part of the heart muscle is deprived of oxygen and nutrients, leading to the death of cardiac tissue.

Understanding these mechanisms is crucial for both prevention and treatment strategies in CAD. Lifestyle changes, medications, and surgical interventions are among the therapeutic options available to manage this disease, aiming to reduce the symptoms and prevent the occurrence of a heart attack by improving blood flow to the heart muscle.

Well, from what I’ve read up on and heard from a few podcasts, Coronary Artery Disease (CAD) seems to stem from the buildup of gunk—plaque—in the walls of the coronary arteries. These arteries are crucial as they feed the heart with all the blood it needs to keep pumping. If they get clogged up, it’s kind of like a clogged pipe in your bathroom, the flow gets restricted. So, when there’s less blood reaching the heart, particularly during exercise or stress, you might feel chest pain or shortness of breath. That’s your heart crying out for more oxygen! If one of those plaques breaks open, it can cause a blood clot on top of the already narrowed arteries—ouch! If the clot blocks the artery, hello heart attack! Trust me, it’s as serious as it sounds.
