Cardiology Symptoms and Risk Factors

Prof. M.D. Kenan Abdurrahman Kara shares what every patient should know about recognizing the early warning signs of heart disease. At Liv Hospital, our cardiologists combine decades of clinical experience with advanced diagnostic technology to catch problems before they become emergencies.

Can a heart attack strike without the classic chest pain? Unfortunately, yes. Prof. Dr. Kara explains why symptoms like unexplained fatigue, shortness of breath, or discomfort in the jaw and back should never be ignored, and when it is time to see a specialist.

Symptoms and Risk Factors

  • Heart disease often develops quietly over many years, but there are usually warning signs before a major event occurs. Invasive cardiology is often brought into the picture when these symptoms start to interfere with daily life or when they suggest a dangerous blockage. Understanding these symptoms is crucial because the sooner you seek help, the more options doctors have to treat you. Ignoring symptoms allows the damage to accumulate, potentially weakening the heart muscle permanently. Risk factors are the conditions or habits that make it more likely for you to develop heart disease. Some of these you can see, like a growing waistline, while others are hidden in your blood, like high cholesterol. An invasive cardiologist considers all these factors when deciding if a catheterization is necessary. They look at the whole picture—your history, your lifestyle, and your current complaints—to determine the probability of a blockage.

Chest Pain and Angina

The most classic symptom that leads a patient to an invasive cardiologist is chest pain, medically known as angina. However, "pain" is not always the word patients use. Many describe it as a pressure, a squeezing sensation, a heaviness, or a tightness. It might feel like an elephant is sitting on your chest or like a tight band is wrapped around your ribs.

Stable Angina

Stable angina is a type of chest discomfort that follows a predictable pattern. It usually happens when you make your heart work harder, such as when walking up a hill, carrying heavy groceries, or dealing with emotional stress. The narrowed arteries cannot supply enough blood to meet the increased demand.

Unstable Angina

Unstable angina is much more serious and is often a sign of an impending heart attack. This type of pain can happen while you are resting, sleeping, or watching TV. It means that blood flow is critically reduced, often by a blood clot that is forming and dissolving in the artery.

Shortness of Breath and Fatigue

Not everyone gets chest pain. Many people, especially those with diabetes or heart failure, experience shortness of breath as their primary symptom. This is known as dyspnea. You might find that you get winded doing simple tasks that used to be easy, like making the bed or walking to the mailbox. This type of condition happens because the heart cannot pump enough blood to the body, or pressure builds up in the lungs.

Unexplained fatigue is another major red flag. This is not just being worn out after a long day; it is a profound exhaustion that feels like your battery has been drained. Patients often describe feeling like their limbs are heavy or that they need to nap frequently. This symptom is often overlooked or blamed on aging, but it can be a sign that the heart is struggling to deliver oxygen to the muscles.

  • The patient may wake up at night, gasping. You may need to prop yourself up with pillows to breathe during sleep while sleeping.
  • You may experience dizziness or lightheadedness after standing up.
  • The inability to complete routine exercise or chores is another common symptom.

Understanding Atherosclerosis

  • Behind many heart attacks and strokes lies a single underlying process: atherosclerosis, the gradual hardening and narrowing of the arteries.

  • Plaque Buildup

    Atherosclerosis begins when cholesterol, fats and other substances build up on the inner walls of the arteries, forming deposits called plaque. Over time this plaque narrows the artery and restricts blood flow. Some plaques are soft and unstable; if one ruptures, it can trigger a blood clot that suddenly blocks the vessel, causing a heart attack.

  • Hardening of the Arteries

    As plaque accumulates, the once-flexible artery walls become thick and stiff. This loss of elasticity forces the heart to work harder to push blood through, raising blood pressure and further straining the cardiovascular system.

Lifestyle Risk Factors

The good news is that many risk factors for heart disease are controllable. These are choices and environments that we can change. Smoking is perhaps the most significant risk factor for needing invasive procedures. The chemicals in tobacco smoke directly damage blood vessels and make blood more likely to clot.

Diet plays a massive role as well. A diet high in saturated fats, trans fats, sugar, and sodium accelerates plaque growth. Being overweight or obese puts extra strain on the heart and is often linked to other risks like diabetes and high blood pressure. A sedentary lifestyle, where one gets little to no exercise, weakens the heart muscle over time.

  • Smoking doubles or triples the risk of heart failure.
  • High cholesterol levels feed the plaque in arteries.
  • Uncontrolled diabetes damages blood vessels aggressively.
  • Excessive alcohol consumption can raise blood pressure.

Uncontrollable Risk Factors

Some risks are written into our biology. Age is a major factor; simply getting older increases the risk of damaged arteries. Men are generally at higher risk at a younger age than women, though a woman's risk increases sharply after menopause when natural protective hormones decline.

Family history is also a powerful predictor. If your parents or siblings had heart disease, especially at a young age, your genetic risk is higher. This doesn't mean you'll get heart disease, but you must be more careful than most. Genetics can influence how your body handles cholesterol and inflammation.

  • Men over 45 and women over 55 are at higher risk.
  • A father with heart disease before 55 increases your risk.
  • A mother with heart disease before 65 increases your risk.
  • Certain ethnicities have higher rates of hypertension and diabetes.

Frequently Asked Questions

What does angina feel like?

Angina is typically described as a pressure, squeezing, heaviness, or tightness in the center of the chest, rather than a sharp or stabbing pain.


Why are diabetic patients at higher risk?

High blood sugar levels over time damage the blood vessels and the nerves that control the heart, increasing the likelihood of developing atherosclerosis and silent heart disease.


Is heart disease hereditary?

Yes, genetic factors can increase your risk, especially if close male relatives developed heart disease before age 55 or female relatives before age 65.


Can stress actually cause a heart attack?

Severe emotional stress can trigger a heart attack or a condition called broken heart syndrome by causing a surge of stress hormones that overwhelm the heart muscle.

Why is sitting for long periods bad for the heart?

Prolonged sedentary behavior slows down blood flow, reduces the body's ability to process fats and sugars, and weakens the heart muscle over time.
