Question Answered step-by-step Read the following article looking for keyword, concepts, and… Read the following article looking for keyword, concepts, and information that might seem useful for a research topic. It is not necessary to read these articles from beginning to end (however you will need to read more than just the abstract). It is helpful to either take notes or highlight the main points or key ideas expressed in the article.  Each Annotation should have the following features and each annotation will be two to three paragraphs:Summarize: Capture the topic, purpose or point, main arguments and conclusions.Assess: Critically evaluate the source for completeness, biases, reliability and usability. Compare with other sources in your bibliography in terms of strengths and weaknesses using the criteria you know best.Reflect: Once you’ve summarized and assessed a source, you need to evaluate how this would fit into a research. Describe how this source would be helpful to you, in which way it shaped your argument (formulates your proposal) and how you will use it in your in your literature to provide a scope of the problem you’re investigating. Article: What is angina?Angina is tightness, squeezing, pressure, or pain in the chest. It occursTrusted Source when an area of the heart muscle receives less blood oxygen than usual.Angina is not a disease but a symptom. It usually happens due to ischemia, when one or more of the coronary arteries becomes narrow or blocked. It is often a symptom of coronary heart disease (CHD).Alone, angina is not life threatening, but it can resemble the symptoms of a heart attack, and it is a sign of heart disease.Receive medical attention if angina occurs unexpectedly, does not go away, or does not respond to rest or medication.TypesThere are several types of angina, including:Stable anginaStable angina occurs when the heart is working harder than usual — for instance, during exercise. It usually lasts around 5 minutesTrusted Source.It has a regular pattern, and a person may experience it for months or years. Rest or medication often relieves the symptoms.Unstable anginaUnstable angina does not follow a regular pattern and usuallyTrusted Source occurs during rest. It mostly results from atherosclerosis, which involves a blockage preventing blood from reaching the heart.The pain lasts longer than 5 minutes and may worsen over time. Rest and medication alone maynot improve the symptoms.Unstable angina can indicate the risk of a heart attack. Anyone with unexpected angina should receive emergency care.Microvascular anginaMicrovascular angina can occur with coronary microvascular disease (MVD). This affects the smallest coronary arteries.As well as chest pain, a person may experience:fatigue and low energysleep problemsshortness of breathMicrovascular angina tends to be more persistent than stable angina. It often lasts longer than 10 minutesTrusted Source and sometimes longer than 30 minutes.Variant anginaVariant angina is rareTrusted Source. Doctors sometimes call it Prinzmetal angina, and it can develop when the body is at rest, often around midnight or the early morning.It happens when a spasm occurs in the coronary arteries. Possible triggers include exposure to cold, stress, medicines, smoking, or cocaine use.It is a chronic condition, but medication can help manage it.SymptomsAngina involves any of the following sensations in the chest:squeezingpressureheavinesstighteningburning or aching across the chest, usually starting behind the breastboneThe pain often spreads to the neck, jaw, arms, shoulders, throat, back, or teeth.Other possible symptoms include:indigestionheartburnweaknesssweatingnauseacrampingshortness of breathThe duration of these symptoms depends on the type of angina.Anyone who experiences severe or persistent chest pain should call 911 or otherwise seek emergency care.Symptoms in femalesIn anyone, angina may stem from CHD or MVD.MVD affects females more often than males, and as a result, the American Heart Association (AHA)Trusted Source explain, females may experience different symptoms that accompany angina.As well as chest pain, which may be sharp, a female with angina may experience:nausea and vomitingabdominal painfatigueshortness of breathThe AHA urge females to seek help for symptoms of heart disease. They emphasize that cardiovascular disease is the main cause of death among females in the United States and that it occurs in almost half of Black American females.
