Mild Heart Attack: How Serious Is It?

When you hear the term “mild heart attack,” many people think it’s not dangerous. But is that true?. A mild heart attack is also known as a minor myocardial infarction. It can cause heart damage if treatment is not received in a timely manner. Therefore, knowing the signs and symptoms of a mild heart attack, the causes, and treatment options are imperative to saving someone's life.

What is a Mild Heart Attack?

A milder heart attack occurs when blood flow to a portion of the heart muscle is damaged due to a partial blockage. The blockage is not complete, thus the amount of heart muscle that has been damaged will be smaller than with a major heart attack.

Don’t let the word “mild” mislead you into thinking it will not cause harm to your heart. The medical profession refers to a mild heart attack as NSTEMI or Non-ST-Elevation Myocardial Infarction (NSTEMI). As the symptoms of a mild heart attack may not be as out of the ordinary as those that accompany a major heart attack, the heart muscle is still deprived of oxygen and the heart will suffer.

What Are Mild Heart Attack Signs and Symptoms?

It is essential to recognize signs of a mild heart attack. The following are common indicators of a mild heart attack:

• Chest discomfort (pressure may be experienced even if you do not have extreme pain in your chest.)
• Shortness of breath (may occur alone or in conjunction with other symptoms.)
• Mild pain radiating to the shoulder, jaw, neck, or back (may occur alone or in combination with chest discomfort.)
• Nausea/vomiting/indigestion (can feel similar to indigestion.) 
• Sweating
• Fatigue/weakness/feeling of tiredness (you may feel fatigue or extreme weakness.)

Symptoms in certain people (particularly older women) are often considerably less apparent than in other groups (e.g., difficulty maintaining balance, feeling of unsteady), therefore early identification is critical!

Seek out help after experiencing chest discomfort lasting greater than 10-15 minutes; regardless of whether you think the discomfort is minor.

How Serious Is a Mild Heart Attack?

Mild heart attacks can cause lasting damage to the heart's tissue, raise the chances of experiencing another more serious heart attack or developing associated complications, such as an irregular heart beat; and may increase your likelihood of being diagnosed with heart failure many years down the road.
The studies show that individuals who fail to pay attention to their early symptoms of a mild heart attack have a higher frequency of suffering a major cardiac event in the future.

Why Does a Mild Heart Attack Happen?

Awareness of the various causes responsible for heart attacks may allow for prevention. The following are some common causes:

• Cholesterol plaque buildup which leads to a restriction in the flow and damaging the muscle.
• Hypertension
• Diabetes (Type 1 & Type 2)
• Tobacco Use
• Obesity
• High Cholesterol
• Sedentary lifestyle with stress associated with daily living.

While the arteries may not be completely blocked, they may be partially blocked or narrowed enough to limit blood flow which results in some degree of damage to the cardiovascular system (heart muscle).

What Is the Best Mild Heart Attack Treatment?

Early treatment helps limit injury and reduce mortality after a heart attack and immediate consultation with the Cardiology Department is essential for proper diagnosis and management;

• Chew an aspirin (if your physician has advised you to do so)
• Get to the hospital as soon as possible – do not delay your trip to the hospital.
• Inside the Hospital, Treatment May Consist Of:
• Blood thinners to stop the clot from growing
• Medications to decrease the workload of the heart
• Angiography (an x-ray procedure) to look for blockages
• Angioplasty (opening of the blocked arteries) or stent placement when necessary
• Recommendations for a change in lifestyle

A primary goal of treatment for a mild heart attack is the restoration of blood flow quickly and preventing additional damage.

How Long Is Recovery Time After a Mild Heart Attack?

Individuals who undergo surgical intervention will experience varied rates of recovery; however, an average timeline is issued above for general reference and use; average stay in the hospital equals between two and five (2 - 5) days; reimplementation of light activity from day of discharge equals between one and two (1 - 2) weeks; and complete recovery will typically take four-to-six (4 - 6) weeks to complete (sometimes a little bit longer); however, individual emotional recovery is just as important as physical recovery; many survivors suffer from feelings of anxiety, fear or depression following a cardiac event.

What things will help speed up recovery?

• Adherence to physician prescribed medications
• Cardiac rehabilitation program participation
• Adherence to normal low sodium/low fat diet
• Daily light exercise as often as allowed by physician
• Use of stress management techniques
• Discontinuance of smoking and limitation of alcoholic beverages

Lifestyle changes are not optional: they are necessary to prevent future cardiac events.

Heart Attack Survivor's Story

During a meeting, Rajesh (48 years old), a businessman, felt some mild chest discomfort. He thought that he was experiencing symptoms of acidity. Although the pain was mild, it continued to persist and did not go away after dinner. After dinner, he felt somewhat short of breath. His wife insisted he go to the hospital for evaluation. After tests were done, it was determined that he had a mild heart attack.

He had angioplasty performed and had a stent placed in order to open up a partially clogged artery to his heart. He got to the hospital in time, and therefore very little heart tissue was actually damaged.

Now he leads a heart-healthy lifestyle by walking, eating balanced diets, and by going to his follow-up appointments. He states often, "If I had waited to see how my symptoms would progress, then I would have been in a far worse situation."

Where Should You Go If You Suspect a Mild Heart Attack?

Make sure to always choose a hospital that has the following:

• 24/7 emergency cardiac care.
• Advanced diagnostic facilities.
• Experienced cardiologists.
• Cardiac catheterization laboratory for immediate percutaneous coronary intervention (angioplasty) procedure.
