Heart Attack - Diagnosis and Treatment

Diagnosis

Common Tests Used

A doctor starts by checking a person’s blood pressure, temperature, and pulse. The doctor may ask about chest pain, discomfort, or other signs like sweating, shortness of breath, nausea, or dizziness.

These symptoms can signal a problem with blood flow to the heart.

The table below lists the main tools doctors use to spot problems with the heart:

Test Name	What It Checks
Electrocardiogram (EKG)	Looks at electrical activity in the heart to find signs of a heart attack or arrhythmias.
Blood Tests	Measures heart proteins (like troponin and creatine kinase) to see if the heart muscle was hurt.
Chest X-ray	Shows the size and shape of the heart and looks for other chest problems.
Echocardiogram	Uses sound waves to see the heart moving and checks if areas are not working right.
Angiogram (Coronary Catheterization)	Puts dye into the blood to spot blockages or plaque in coronary arteries.
Cardiac CT or MRI	Makes detailed images to find heart damage or check for coronary artery disease (CAD) and which areas do not get enough blood.

These tests help doctors find out if someone had a heart attack or if blocked arteries are present.

Doctors usually perform an electrocardiogram (EKG) right away to check for changes in heart rhythm and damage. Blood tests check for certain markers in the blood that show heart muscle injury.

Other tests like X-rays, echocardiograms, or cardiac CT/MRI give more information about the heart’s health. Doctors use angiography to locate blockages or blood clots. This helps plan the right treatment.

Additional Facts About Heart Attack Screening

Doctors combine a person’s medical history, physical exam, and test results to make a diagnosis. They may ask about family history of stroke, diabetes, high triglycerides, or previous angina.

Risk factors such as high blood pressure, diabetes, smoking, and high cholesterol increase the chance of heart disease or heart attacks. Sometimes symptoms like heartburn or a cold sweat also appear during a heart attack.

Doctors look for other conditions, such as arrhythmias, that may cause similar symptoms. Regular checkups help spot problems before a heart attack happens.

Treatment

Medicines Used for Heart Attacks

Doctors often start treatment right away with oxygen to help the body and heart get more oxygen. They also give several common medicines, including:

Aspirin: Prevents clots from forming. Doctors give it as soon as they suspect a heart attack.
Clot-Busting Drugs (Thrombolytics or Fibrinolytics): Break up blood clots blocking heart arteries. Early use limits damage.
Other Blood Thinners: Given by IV, these reduce the chance of more clots forming.
Nitrate Vasodilator: Widens blood vessels and boosts blood flow to the heart. Doctors may give it under the tongue, as a pill, or as an injection.
Opioid Agonist: Used for pain if nitroglycerin doesn’t work.
Beta Blockers: Slow the heart and lower blood pressure. These medicines protect the heart muscle and may prevent more damage.
Angiotensin-Converting Enzyme (ACE) Inhibitors: Lower blood pressure and ease strain on the heart, lowering the risk of more heart failure.
Statins: Lower cholesterol and help prevent further narrowing of the arteries.

Most people with heart attacks receive several of these medicines together. Doctors choose the best mix for each patient.

Procedures and Surgeries to Restore Blood Flow

Sometimes, medicine alone is not enough, and a procedure is needed to reopen blocked heart arteries.

Coronary angioplasty with stent placement: In this procedure, doctors insert a thin tube (catheter) into a blocked artery. They use a small balloon to open the artery, then place a stent (wire mesh tube) to keep the vessel open. Some stents have medicine to help prevent the artery from narrowing again.
Coronary artery bypass surgery (CABG): If arteries are badly blocked, surgeons take a healthy blood vessel from another part of the body and attach it to the heart, allowing blood to bypass the blockage.

Both methods aim to quickly restore blood flow and prevent more heart tissue from dying. Percutaneous coronary intervention (PCI) is more common right after a heart attack.

Bypass surgery helps people with more severe damage or blockages that stents cannot fix. Possible problems include bleeding, infection, or more heart damage, but these are less likely if doctors act quickly.

Heart Health Recovery Programs

Many people join a cardiac rehabilitation program after the emergency. Nurses, doctors, and therapists lead these programs.

Cardiac rehab helps patients:

Exercise safely
Learn about a heart-healthy diet
Manage stress
Return to normal daily activities

Cardiac rehab starts in the hospital and often continues for weeks or months at home or at a rehab center.

Self-Care

Taking care of your heart means making steady improvements in daily habits.

Physical activity is important. Try to get at least 30 minutes of moderate exercise most days. Activities like brisk walking, swimming, or biking strengthen the heart and lower stress.

A healthy eating plan can lower the chance of problems like high cholesterol and high blood pressure.

Focus on foods such as fruits, vegetables, whole grains, and lean proteins. Limit foods with saturated fat, trans fat, salt, and added sugars.

Foods to Choose	Foods to Limit
Fruits & vegetables	Fried foods
Whole grains	Processed snacks
Lean meats & fish	Sugary drinks
Beans & legumes	High-salt foods

Weight control is key. Losing extra pounds reduces strain on the heart and helps manage cholesterol and blood pressure.

Smoking harms the heart. Quitting is the best choice. Avoid secondhand smoke too.

Check in with a health care provider regularly. They can help watch for problems like high blood pressure or high cholesterol, which often do not show clear signs.

Stress affects heart health. Activities like exercise, talking with friends, or relaxing hobbies can lower stress levels.

Moderation matters when drinking alcohol. For most adults, this means no more than one drink a day for women and two drinks a day for men.

Building these habits helps people manage their heart health and lower the risk of future heart problems.

Getting Support and Handling Stress

Open communication helps recovery. People who have had a heart attack benefit from talking about their feelings or concerns with healthcare professionals, family, or friends.

Joining a support group can also provide comfort and connect people with others who have similar experiences.

If feelings of sadness, worry, or depression come up, reach out for help. Cardiac rehabilitation programs assist with physical recovery and provide emotional support.

Returning to Intimacy After a Heart Event

Concerns about resuming sexual activity after a heart attack are common. In many cases, it is safe to have sex after recovery, but medical advice should be sought first.

Factors like physical comfort, emotional readiness, and past sexual health matter.

Some medications for heart conditions may affect sexual function. If issues come up, speak with a healthcare provider. Partners should support each other and talk openly about any challenges.

Getting Ready for Your Visit

Steps You Can Take Before Your Appointment

Preparing for a heart specialist appointment helps make the visit smoother and more useful.

Before the day arrives, check for any special instructions. Some tests may require fasting or avoiding certain foods or drinks, especially before blood tests like cholesterol checks.

Write down important details before the appointment.

Consider making a checklist like the one below:

What to Bring	Details to Include
List of Symptoms	Note all symptoms, even those you think are unrelated, and when they started.
Family Medical History	Include heart disease, stroke, high blood pressure, diabetes, early heart problems.
Personal Health Information	Include recent life changes or major stresses.
Medications and Supplements	List names, doses, and frequency for everything you take.
Questions for the Doctor	Prepare questions about your risk, treatment, diet, exercise, and monitoring.

Bring a friend or family member if you can. They may remember advice or information you miss. This can be especially helpful if you feel anxious.

When preparing questions, here are some examples to consider:

What types of tests will I need to check my heart health?
Are there foods I should eat more of or avoid?
How often should I have check-ups or tests?
What level of exercise is safe for me?
How should I handle my other medical conditions along with my heart risk?

Ask any questions that come to mind. The doctor is there to help.

What Your Doctor May Ask You

The healthcare provider will likely ask several questions to understand your concerns and risks.

Knowing what might come up helps you prepare honest, thorough answers.

Typical questions may include:

How long have you been experiencing symptoms, and how bad are they?
Do you feel symptoms all the time, or do they come and go?
Is there anything that makes your symptoms better or worse?
If you have chest pain, does rest help it go away?
Do certain activities or movements make your symptoms worse?
Have you been diagnosed with high blood pressure, diabetes, or high cholesterol in the past?

Providing clear answers helps your provider understand your situation. If you forget details, your written list will help. The doctor may also examine you, do blood work, or run other simple tests during your visit.

Be ready for possible procedures such as an EKG, blood pressure check, or cholesterol test.

Sample Question Table

Example Question From Doctor	How to Prepare
How severe are your symptoms?	Use a scale (for example, 1–10) if you can.
Are symptoms constant or do they come and go?	Keep a symptom diary if needed.
What improves or worsens the symptoms?	Track changes during activities or rest.
Does chest pain improve when you rest?	Note any patterns you notice.
Do activities make your pain worse?	List types of activities that bring pain.
Have you had certain conditions before?	Bring any past health records, if possible.

Being honest and thorough gives your doctor more tools to help you.
