Heart Attack vs. Cardiac Arrest: What you need to know about them, part 1


As a nurse on a cardiac floor, I have frequently been asked (or had to explain) the difference between a heart attack and a cardiac arrest. People often assume they are the same thing. 


A heart attack can lead to a cardiac arrest, but they are not the same thing.


This post will deal with heart attacks. 


What is a heart attack?

Are you at risk for a heart attack?

What are the symptoms of a heart attack?

What can you do to prevent a heart attack?


A heart attack occurs when one of the blood vessels (coronary arteries) supplying blood to your heart muscle is blocked, oxygen can no longer reach the area, and the heart muscle begins to die; but the heart has not stopped beating. A heart attack can lead to a cardiac arrest, when the heart stops beating entirely. 


Both of these conditions are life-threatening emergencies. Call 9-1-1 immediately if you are someone around you is having symptoms of a heart attack. Do not attempt to drive to the hospital yourself; it is always better to call for an ambulance.



What causes a heart attack?



Most heart attacks are caused by coronary artery disease (CAD), a condition that causes fatty plaque build-up in the arteries. CAD is also called atherosclerosis or "hardening of the arteries." When this plaque leads to a blockage in the artery, a heart attack may result.


Rarely, a heart attack can happen when one of the coronary arteries is blocked by a spasm. 


Risk Factors for a heart attack


Some risk factors for a heart attack can be controlled. These include:


  • High blood pressure
  • High cholesterol
  • Obesity
  • Lack of exercise
  • Smoking
  • Drinking too much alcohol
  • Diabetes


Other factors cannot be controlled. These include:


Symptoms of a heart attack


Symptoms of a heart attack can include:


  • Chest pain
  • Heartburn or indigestion
  • Pain in your chest that radiates to your jaw or arm
  • Dizziness or lightheadedness
  • A "cold sweat"
  • Nausea
  • Shortness of breath
  • Irregular heart rate or palpitations
  • Weakness



How can I prevent a heart attack?



As mentioned above, not all risk factors for a heart attack can be controlled, but a heart-healthy diet and exercise can help prevent or postpone heart attacks for most people.


Here are some practical ways to lower your risk of having a heart attack:


  • Eat a heart-healthy diet.
  • Get in at least 150 minutes of moderate intensity exercise every week, 30 minutes most days is a good goal to shoot for.
  • Stop smoking.
  • Avoid alcohol.
  • Lose excess weight by modifying your diet and exercise routine.
  • Take all your heart and blood pressure medications as prescribed by your doctor. 
  • Control your diabetes by diet modification, exercise, and taking your medications as prescribed.



What should I take away from this article?



A heart attack is a life-threatening emergency. Call9-1-1 if you are someone near you is experiencing symptoms of a heart attack.


Learning the risk factors and symptoms of a heart attack can help you react quickly if you ever encounter someone having a heart attack.


Eating a healthy diet and exercising most days a week will go a long way in the prevention of a heart attack.


Making lifestyle changes today can lead to a much better life in the future.




The post next will continue to discuss heart attacks:


How is a heart attack diagnosed?

How is a heart attack treated?

What complications can result from a heart attack?




Then we will dig into cardiac arrests in some detail.

A Comparative Overview for Pain Management Steroid injections and Platelet-Rich Plasma (PRP) injections are two commonly used pain management treatments. While both aim to alleviate pain and promote healing, they have different mechanisms of action and long-term effects . What Are Steroid Injections ? Corticosteroids are potent drugs used extensively across various medical fields to manage a broad spectrum of conditions, making them one of the most widely prescribed drug classes in the world. They can be administered via nearly every route, including direct injection into painful or inflamed joints. "Corticosteroids" typically refers to the class of drugs that produce glucocorticoid effects. Glucocorticoids are stress hormones that regulate numerous physiologic processes within the body. They have vasoconstrictive, immunosuppressive, and anti-inflammatory effects and play a role in metabolism. What do steroid injections treat? Corticosteroids function by suppressing the immune system and reducing inflammation within the body. They inhibit the production of the body's pro-inflammatory chemicals, leading to decreased inflammation and, consequently, pain. They are prescribed for hundreds of medical conditions, including: Allergic and autoimmune disorders Adrenocortical secretion disorders Infections and inflammation Pathologic hypoglycemia Organ and graft rejections Neurological disorders Hypercalcemia Blood disorders Skin disorders Shock What are the side effects of steroid injections? Although steroids are known to some as “wonder drugs,” they impact various bodily systems, including metabolism, water and electrolyte balance, the central nervous system, and blood cells. As a result, they are associated with many adverse side effects, especially when administered in large doses or over extended periods. Adverse effects may occur in up to 90% of individuals who take them for longer than sixty days. These side effects may include: Suppression of the hypothalamic-pituitary-adrenal axis Gastrointestinal disturbances Osteoporosis and fractures Psychiatric disturbances Carpal tunnel syndrome Cardiovascular disease Immunosuppression Cushingoid features Hyperglycemia Skin disorders Glaucoma Myopathy Cataracts Diabetes The risk of adverse side effects is particularly high when taken systemically. However, side effect occurrences vary when administered as local injections for pain management. Data indicates that steroid injections into joints and the spine can produce systemic effects that can last for weeks. When assessing the risk factors associated with steroid injections, healthcare providers must consider all types and doses of steroids the person is taking, including both oral and injectable forms. Additionally, special caution is advised for certain populations, such as those who may undergo surgery soon, postmenopausal women, and individuals with diabetes. What is Platelet-Rich Plasma (PRP) ? Platelet-rich plasma (PRP) injections use an individual's own blood to promote cellular regeneration. Through the extraction and reinjection of platelets, growth factors, and other bioactive proteins from the person's blood, PRP therapy offers long-lasting improvements, sustained pain relief, and enhanced tissue function. What do PRP injections treat? PRP injections can stimulate healthy cell growth, reduce inflammation, promote tissue repair, form new blood vessels, rejuvenate the skin and hair, and accelerate recovery after a traumatic injury. It can treat a wide range of conditions, including: Pain resulting from traumatic injury or degenerative conditions such as arthritis and chronic back pain Musculoskeletal conditions Tendinopathies and tears Compressive neuropathy Scars and stretch marks Osteochondral lesions Rheumatoid arthritis Erectile dysfunction Muscular injuries Plantar fasciitis Vaginal atrophy Osteoarthritis Epicondylitis Infertility Psoriasis Wounds Bursitis Vitiligo What are the side effects of PRP? Since PRP is derived from the person's own blood, the risk of allergic reactions or rejection is significantly lower compared to other injectables, such as steroids. PRP typically does not cause major side effects, though you may experience some soreness or bruising at the injection site. In rare cases, potential side effects may include: Tissue damage Nerve injuries Bleeding Infection Comparison of Steroid Injections and PRP Injections A study in the Journal of Orthopaedic Surgery and Research compared steroid injections with PRP injections in patients with mild to moderate symptomatic knee osteoarthritis (OA). The findings indicated that both treatments were safe and effective in improving short-term pain and functioning, with no significant differences observed. However, PRP therapy demonstrated superior outcomes in the long term, with benefits extending up to one year. Additionally, a literature review in Cureus Journal of Medical Science analyzed multiple studies comparing steroid injections with PRP in lumbar spondylosis and sacroiliac arthropathy. The review found that PRP was equally as effective, if not superior, to steroid injections in the short term. Neither treatment was associated with major complications, and there were no significant differences in minor complications between the two. The review concluded that both PRP and steroid injections are safe and effective for treating lumbar spondylosis and sacroiliac arthropathy, with some evidence that PRP may offer more benefits in the long term. Research has confirmed that both steroid and PRP therapy are valuable options for pain management and tissue healing. Steroid injections offer potent anti-inflammatory benefits that can provide immediate relief. However, their systemic side effects and limited duration of efficacy should be carefully considered, especially in high-risk populations. While PRP may take longer to show results, its long-term benefits make it an increasingly popular choice for treating various conditions. Ultimately, the choice between these treatments should be based on the specific needs of the individual patient, with careful attention to the patient's medical history.
