Acute coronary syndrome (ACS) results from acute obstruction of a coronary artery which is responsible for a high mortality rate worldwide. The consequences depend on the degree and location of the obstruction and vary from unstable angina to non-ST segment elevation myocardial infarction (NSTEMI), ST-segment elevation myocardial infarction, and sudden cardiac death. The symptoms are similar in each of these syndromes (except for sudden death), involving chest discomfort with or without dyspnea, nausea, and diaphoresis. The diagnosis is possible; thanks to the electrocardiogram that is essential and the existence or absence of serological markers. In addition to these initial resources, other diagnostic methods are noteworthy, such as stress electrocardiogram, echocardiography, nuclear cardiology, computed tomography angiography, and exercise test. Other necessary measures are the stratification of the identified cases according to the degree of risk, availability of a coronary intensive care unit, and the establishment of the opportune treatment that consists of oxygen therapy, analgesia, sedation, antiplatelet, anticoagulants, nitrates, beta-blockers drugs, reperfusion of emergency with fibrinolytic drugs, percutaneous intervention or, occasionally, myocardial revascularization surgery to provide the recovery and consequently a better quality of life for the patient. This brief review aims to discuss the available diagnostic and therapeutic resources and the appropriate risk stratification for adequate care for the victims of acute coronary heart disease promptly in a hospital setting.

Background: For decades, static stretching has been the standard benchmark for training programs, because it has been shown to increase flexibility compared with other methods of stretching. Objective: The current study investigated and compared the effects of active dynamic stretching and passive static stretching on hamstring tightness. Methods: For this experiment, 64 female students were enrolled and randomly assigned to active dynamic or passive static stretching groups (n = 32 each). The first and second experimental groups were trained with repetitive dynamic stretching and static stretching exercises, respectively. Exercises were performed 10 times per limb, 3 times per day, 5 days per week for 4 weeks. Hamstring muscle length measurements were repeated in weeks 2 and 4. Statistical analysis of the results was performed by t-test and repeated measures ANOVA using SPSS 15. Results: Both experimental groups showed significant improvements in the active knee extension range of motion during the intervention (P < 0.001). However, active stretching showed better results and had a greater effect on range of motion in comparison with static stretching.Conclusion: Active dynamic training can be considered a suitable method for increasing the flexibility of the hamstring muscle and, consequently, reducing the complications and problems associated with hamstring tightness.
