Myocardial Infarction
Myocardial infarction or acute myocardial infarction are the other terms for heart attack. The heart attack occurs when the blood supply to some certain areas to heart is disrupted and the heart muscle lacks oxygen and therefore gets damaged. In coronary arteries, which supply the heart, sometimes an obstruction may also occur. What this means is that an unstable plaque that consists of fat, cholesterol and white blood cells is formed and obstruct the vessel.
The symptoms of myocardial infarction are as the following: chest pain (which travels to left arm or left neck), shortness of breath, sweating, nausea, vomiting, abnormal heart rate, anxiety and other factors. It is also worth noting that 64 percent of patients who have had an heart attack does not have chest pain as a symptom, which is called “Silent Heart Attack”.
What contributes to heart attack is aging, smoking, hypertension, high levels of cholesterol, LDL and fat, diabetes, obesity, inadequate physical activity, chronic kidney disorders, consumption of excessive levels of alcohol and substances.
The immediate treatment for the heart attack is to use Aspirin, which prevents the formation of blood clots and Nitroglycerin which dilates the vessels and relieves chest pain and also provides oxygen supply to the heart.

Iron Deficiency and Iron Deficiency related anemia contributes to several diseases worldwide. In 2016, more than 1.2 billion cases of iron deficiency anemia were reported. Iron deficiency anemia affects children, women in pre-menopause and people in low and middle income countries more.
In the ever-evolving landscape of healthcare, the discipline of pharmacoeconomics has emerged as a vital tool for maximizing the value of healthcare resources and optimizing patient outcomes.
In the realm of healthcare, effective communication is paramount, especially when it comes to ensuring therapeutic safety for patients.
Once the Vitamin B12 is absorbed, it plays a key role as a cofactor in the synthesis of DNA, fatty acids or myelin. Therefore, Vitamin B12 deficiency could lead to both hematologic and neurologic symptoms.
