Myocardial Infarction

Myocardial Infarction

Myocardial Infarction
Myocardial infarction (MI) is ischemic necrosis of the heart muscle caused by an acute disruption of its blood supply. It is one of the most dangerous cardiovascular diseases and remains one of the leading causes of death worldwide.
According to statistics, most cases occur in individuals aged 45–65. Men tend to develop the disease at a younger age than women. In recent years, due to preventive measures in developed countries, the incidence of infarction has somewhat decreased, but it remains a major global health problem.

Etiology and Risk Factors

The main cause of myocardial infarction is atherosclerotic damage to the coronary arteries. After rupture of an atherosclerotic plaque, a thrombus forms, blocking the artery and leading to myocardial ischemia.

The main risk factors are:

• High blood pressure.
• High cholesterol or lipid disorders.
• Diabetes mellitus.
• Smoking.
• Overweight and physical inactivity.
• Age, especially over 50.
• Stress and unhealthy lifestyle.

Clinical Picture

1. The main symptom of MI is a compressive, burning, or pressing chest pain lasting more than 20 minutes.
2. The pain may radiate to the left arm, neck, lower jaw, or back.
3. It is often accompanied by cold sweats, weakness, shortness of breath, and nausea.
4. In elderly patients and those with diabetes, pain may be mild or absent.

Classification

Myocardial infarction is classified according to several principles.
1. Based on ECG findings:
• ST-segment elevation MI (STEMI).
• Non-ST-segment elevation MI (NSTEMI).
2. Based on localization:
• Anterior wall infarction.
• Posterior wall infarction.
• Lateral, inferior, or extensive infarction.
3. Based on stages:
• Early stage — first 24 hours.
• Acute stage — up to 7 days.
• Subacute stage — up to 4 weeks.
• Chronic stage — formation of myocardial scar.

Diagnosis

1. Diagnosis is based on three main criteria:
• Typical clinical symptoms.
• ECG changes — ST-segment elevation or depression, Q-wave formation.
• Elevated biochemical markers of myocardial injury (Troponin I/T, CK-MB).
2. Echocardiography helps detect areas of segmental hypokinesia or akinesia.

Complications

The complications of acute myocardial infarction are divided into early and late stages.
Early Complications (from the first hours to the first days)
1. Arrhythmias:
• Ventricular tachycardia or fibrillation.
• Atrioventricular block.
• Sinus bradycardia or tachycardia.
2. Heart failure:
• Acute left ventricular failure.
• Pulmonary edema.
3. Cardiogenic shock.
4. Myocardial rupture (often on the 3rd–5th day):
• Free wall rupture leading to cardiac tamponade.
• Ventricular septal rupture.
• Papillary muscle rupture leading to acute mitral insufficiency.
5. Early fibrinous pericarditis.
Late Complications (weeks to months)
1. Myocardial aneurysm, acute or chronic.
2. Impaired ejection of blood from the heart.
3. Thrombosis in the aneurysmal cavity.
4. Thromboembolic complications — cerebral stroke or pulmonary embolism.
5. Late pericarditis (Dressler’s syndrome) of autoimmune origin.
6. Chronic heart failure.
7. Recurrent infarction or ischemic attacks.

Treatment

The main goal of treatment is to restore coronary blood flow as quickly as possible to prevent myocardial damage. Coronary angiography is considered the “gold standard” because it identifies the occlusion site and allows restoration of circulation. Thrombolysis is most effective during the first hours after onset, while percutaneous coronary intervention (PCI, stenting) is the preferred method. If PCI is not possible, coronary artery bypass grafting (CABG) is performed.
Additional medications are used, including morphine for pain relief, antiplatelet therapy with aspirin and P2Y12 inhibitors, heparin for anticoagulation, as well as beta-blockers and ACE inhibitors to reduce cardiac workload. This comprehensive approach lowers the risk of complications and improves recovery outcomes.

Prevention

Secondary prevention is essential after myocardial infarction to reduce the risk of recurrence and complications. Patients should remain under regular cardiologist supervision, with strict control of blood pressure, glucose, and lipid levels. Cardiac rehabilitation exercises play an important role in restoring cardiac function. Prescribed medications must be taken consistently and according to medical recommendations.
Myocardial infarction is a severe but controllable disease if diagnosed and treated in time. Early detection and appropriate therapy can save lives and prevent complications. Prevention begins with every individual — through a healthy lifestyle and regular medical check-ups.
Migraine or ordinary headache? How to tell the difference
29 May 2026
Almost everyone experiences headaches from time to time. Stress, lack of sleep, dehydration, or long hours in front of a screen can all lead to head pain. But sometimes what seems like an ordinary headache may actually be a migraine. Although many people use the words “migraine” and “headache” interchangeably, they are not the same condition. A migraine is a more complex neurological disorder that often comes with additional symptoms beyond head pain. Understanding the difference can help you choose the right treatment and know when it is time to seek medical help. What does an ordinary headache feel like? The most common type is a tension headache. It usually causes: • A dull, aching pain • Pressure or tightness around the forehead or sides of the head • Mild to moderate discomfort • Pain on both sides of the head Tension headaches are often linked to stress, anxiety, muscle strain, fatigue, or poor sleep. While uncomfortable, they are usually manageable and often improve with rest, hydration, or over-the-counter pain relievers. What makes a migraine different? A migraine is typically more intense and disruptive than a regular headache. The pain is often throbbing or pulsating and may affect one side of the head, although both sides can sometimes be involved. Migraine attacks can last anywhere from several hours to even a few days if untreated. In addition to head pain, migraines may cause: • Nausea or vomiting • Sensitivity to light, sound, or smells • Blurred vision • Neck pain or fatigue • Difficulty concentrating For many people, normal daily activities become difficult during a migraine attack. Some need to rest in a dark, quiet room until the symptoms improve. What is migraine aura? Some people experience warning signs before the migraine begins. This is called aura. Aura may include: • Flashing lights or zig-zag lines • Tingling or numbness in the face or hands • Temporary vision changes • Difficulty speaking clearly These symptoms usually develop gradually and may last up to an hour before the headache starts. Other types of headaches Certain headaches can sometimes be mistaken for migraines. Sinus headache. Sinus headaches usually cause pressure around the forehead, cheeks, or nose and are often accompanied by nasal congestion or thick mucus related to infection.Cluster headache. Cluster headaches are rare but extremely painful. They usually cause sudden stabbing pain around one eye, often with tearing or a stuffy nose. Unlike migraines, cluster headaches appear suddenly and typically last a shorter time.Common migraine triggers Migraine attacks can be triggered by different factors, including: • Stress • Hormonal changes • Lack of sleep • Skipping meals • Dehydration • Weather changes • Certain foods or alcohol • Excess caffeine Triggers vary from person to person, and keeping a headache diary may help identify patterns. When should you see a doctor? Occasional headaches are common, but medical evaluation is important if: • Headaches happen frequently • Pain interferes with daily activities • Over-the-counter medications stop helping • You experience nausea, vision changes, or neurological symptoms • A sudden severe headache appears unexpectedly A doctor may recommend further evaluation to rule out other neurological or medical conditions. Migraines can significantly affect quality of life, but with proper diagnosis and treatment, many people are able to reduce both the frequency and severity of attacks.
Why Hair Loss Happens: Hormones, Stress, or Vitamin Deficiency?
25 May 2026
Losing some hair every day is normal. Most people shed around 50–100 hairs daily as part of the natural hair growth cycle. Problems begin when hair falls out faster than it can grow back, leading to noticeable thinning or bald patches. Hair loss, also called alopecia, can affect both men and women and may develop gradually or suddenly. Common Causes of Hair Loss Genetics and Hormones The most common cause is hereditary hair loss, known as androgenic alopecia. Men often develop a receding hairline or thinning at the crown, while women usually notice overall thinning and a wider hair part. Hormonal changes from pregnancy, menopause, thyroid disorders, or conditions like PCOS can also trigger hair shedding. Stress and Illness Physical or emotional stress may cause temporary hair loss. Surgery, illness, rapid weight loss, or difficult emotional experiences can push more hairs into the shedding phase. This often appears a few months after the stressful event. Vitamin Deficiencies Low levels of iron, protein, vitamin D, and certain B vitamins may weaken hair growth. Vitamin D is especially important because it helps support hair follicles. Deficiency may also cause fatigue, muscle weakness, and low mood. Other Possible Reasons Hair loss can also result from: • Autoimmune conditions such as alopecia areata • Certain medications, including chemotherapy • Scalp infections • Tight hairstyles that pull on the hair • Frequent bleaching or heat styling When Should You See a Doctor? You should seek medical advice if you notice: • Sudden or excessive hair shedding • Bald patches • Itching or pain on the scalp • Hair loss together with fatigue or hormonal symptoms Doctors may recommend blood tests to check iron levels, thyroid function, or vitamin deficiencies. Can Hair Loss Be Treated? Treatment depends on the cause. Correcting nutritional deficiencies or hormonal imbalances may help reduce shedding. Other options include topical treatments, PRP therapy, and hair transplantation in selected cases. To support healthy hair growth: • Eat a balanced diet • Avoid tight hairstyles and excessive heat • Manage stress • Treat medical conditions early Although hair loss can be frustrating, many cases improve once the underlying cause is identified and treated.
Kidney stones: Causes, symptoms, and treatment
20 May 2026
Kidney stones are hard deposits that form inside the kidneys when minerals and salts in the urine begin to stick together and create crystals. These stones can be tiny like a grain of sand or grow much larger over time. Some pass out of the body without causing symptoms, while others may block the urinary tract and lead to severe pain or complications. Kidney stones are a common urinary system problem and can affect people of all ages, although they are seen more often in adults, especially men. Once a person develops a kidney stone, the risk of getting another one in the future becomes higher. Why do kidney stones form? Urine naturally contains substances such as calcium, oxalate, uric acid, and other minerals. Normally, these substances dissolve in liquid and leave the body safely. However, when urine becomes too concentrated or certain chemicals rise to high levels, crystals may start forming and gradually turn into stones. Several factors can increase the risk of kidney stones, including: • Not drinking enough water • Diets high in salt, sugar, or animal protein • Family history of kidney stones • Obesity and metabolic disorders • Recurrent urinary tract infections • Certain medications or high-dose supplements • Digestive diseases or previous intestinal surgery Some medical conditions such as gout, diabetes, hyperparathyroidism, or cystinuria can also make stone formation more likely. Main types of kidney stones There are several different kinds of kidney stones, and each develops for different reasons: • Calcium stones – the most common type, usually formed from calcium combined with oxalate or phosphate • Uric acid stones – often linked to diets rich in meat and seafood • Struvite stones – associated with urinary tract infections and may grow quickly • Cystine stones – a rare inherited form caused by a genetic condition Understanding the type of stone is important because it helps guide treatment and prevention. Symptoms of kidney stones Small stones may pass unnoticed, but larger stones can become trapped in the urinary tract and cause intense symptoms. Pain usually begins suddenly and may come in waves. Common symptoms include: • Sharp pain in the lower back, side, or abdomen • Pain spreading toward the groin • Blood in the urine • Burning or pain during urination • Frequent urge to urinate • Nausea and vomiting • Cloudy or foul-smelling urine • Fever or chills if infection develops In some cases, kidney stones may block urine flow and lead to swelling of the kidney, infection, or even kidney damage if left untreated. How are kidney stones diagnosed? Doctors use several methods to confirm kidney stones and determine their size and location. Diagnosis may include: • Urine analysis to check for blood, crystals, or infection • Blood tests to evaluate kidney function and mineral levels • Ultrasound examination • CT scan or X-ray imaging If a stone passes naturally, doctors may ask the patient to collect it for laboratory analysis. Treatment Treatment depends on the size of the stone, its location, and the severity of symptoms. Small stones often pass on their own within several days or weeks. During this time, patients are usually advised to drink plenty of fluids and may receive medication to reduce pain or help relax the urinary tract. Larger stones or stones causing blockage may require medical procedures such as: • Shock wave lithotripsy (ESWL) – sound waves break the stone into smaller fragments • Ureteroscopy – a thin instrument is passed through the urinary tract to remove or break the stone • Percutaneous nephrolithotomy – used for very large stones through a small incision in the back Traditional surgery is now less common but may still be needed in rare complicated cases. Can kidney stones be prevented? Although kidney stones can recur, many cases are preventable with lifestyle changes. Prevention usually focuses on reducing the concentration of stone-forming substances in urine. Helpful prevention tips include: • Drink enough water throughout the day • Reduce salt and sugary foods • Avoid excessive animal protein • Maintain a healthy body weight • Treat urinary infections promptly • Follow medical advice regarding supplements and medications Some people may also need a personalized diet plan depending on the type of stone they develop. Early diagnosis and proper treatment help prevent complications and protect kidney health.
Why we need folic acid
16 May 2026
Folic acid, also known as vitamin B9, is an important vitamin that helps the body grow, repair, and function properly. It is involved in the production of new cells, making red blood cells, and supporting healthy brain and nervous system function. Although folic acid is most commonly associated with pregnancy, it is actually essential for people of all ages. Folic acid is the synthetic form of folate, a vitamin naturally found in foods. Since the body cannot store large amounts of it, regular intake through food or supplements is important. This vitamin has several important functions in the body, including: • Supporting cell growth and DNA production • Helping form healthy red blood cells • Supporting brain and heart health One of the most well-known benefits of folic acid is its role during pregnancy. In the early weeks of pregnancy, it helps the baby’s brain and spinal cord develop properly. Adequate folic acid intake significantly lowers the risk of serious birth defects such as spina bifida. Because these changes happen very early — often before a woman even knows she is pregnant — doctors recommend that women of reproductive age get enough folic acid daily. A lack of folic acid may lead to folate-deficiency anemia, a condition in which the body cannot produce enough healthy red blood cells. Common symptoms may include: • Fatigue and weakness • Pale skin • Dizziness or shortness of breath Folic acid may also contribute to overall wellness by helping regulate homocysteine, a substance linked to heart disease when present at high levels. Some studies also suggest that healthy folate levels may support memory, mood, and cognitive function. Good dietary sources of folate include: • Leafy green vegetables • Beans and lentils • Citrus fruits • Eggs and nuts • Fortified cereals and grain products Most adults need around 400 micrograms of folic acid daily, while pregnant women usually require higher amounts. Supplements may be recommended in certain situations, especially during pregnancy or in people with absorption problems. Overall, folic acid is a small but essential nutrient that supports many important processes in the body. From healthy blood cells to proper fetal development, getting enough folic acid is an important part of maintaining good health. Check your folic acid levels now at Dalimed Medical Center.
