When did cardiovascular disease become a problem?
Heart disease was an uncommon cause of death in the US at the beginning of the 20th century. By mid-century it had become the commonest cause. After peaking in the mid-1960s, the number of heart disease deaths began a marked decline that has persisted to the present.
How was heart disease treated in the 1960s?
In the 1960s, there was no treatment for a heart attack. If they survived, victims were confined to a hospital bed, given painkillers and told to take complete rest. If they died in their 50s or 60s, like Robert's father, it was considered a fact of life.

How were heart attacks treated in the 1980s?
1970-1980s: * In 1986, streptokinase was given through the vein to dissolve a blood clot in a patient with heart attack. This led to decreased risk of death from heart attacks.
Why has heart disease increased since 1900?
During the first half of the 20th century, doctors and scientists focused on treating infectious diseases -- for example, developing new drugs to cure pneumonia and virtually eradicate tuberculosis. These dramatic advances enabled people to live longer -- and inadvertently opened the door to coronary heart disease.
When did we start treating hypertension?
The late 1940s and 1950s heralded a dramatic change in the approach to the treatment of hypertension. While there were still some physicians who continued to have doubts regarding the significance of hypertension, most had accepted the fact that increased pressure increased risk for cardiovascular disease.

What is the purpose of a cardiovascular history?
The cardiovascular history is obtained to identify evidence of organic heart disease or symptoms that suggest the presence, or possible presence, of cardiovascular abnormalities.
Why is the age of a heart murmur important?
In addition, a history of any physical restrictions placed on the patient at the time of diagnosis should be sought.
What are some examples of past events?
A classic example is the patient who states that his mother told him never to take penicillin, but the reason for this restriction is not known. A febrile illness accompanied by a systolic murmur becomes rheumatic fever (especially if the illness occurred during the era when this disease was very common). Rheumatic fever then becomes translated into rheumatic heart disease when the patient, years later, complains of fatigue. Patients with a history of shortness of breath or swelling of the lower extremities may have acquired a label of congestive heart failure, and may be placed on a digitalis preparation.
What is accurate history?
Accurate history taking is an acquired skill that is perfected through experience. Details of the history may vary according to the physical and emotional status of the patient; his or her educational, cultural, and economic background; and the manner in which questions are asked. Direct questioning, questioning of family members and spouse, and review of medical records may be required.
How long do you stay in hospital for a heart attack?
A history of heart attacks as a child, or "ten heart attacks since 1970," should be viewed with some skepticism unless documentation has been obtained. Today, the majority of patients with myocardial infarction experience a hospital stay of at least a week. Patients who state they were hospitalized for only a day or two, or were discharged from the emergency room, usually were not suffering from acute infarction. Further documentation is needed.
Is a search for cardiac risk factors appropriately incorporated into the past history?
A search for cardiac risk factors is also appropriately incorporated into the past history. Has the patient ever been told he or she has high or low blood sugar ? (The latter is not a risk factor, but suggests that a blood glucose may have been drawn in the past.) Has the patient had high cholesterol or triglycerides, or high or low blood pressure? Has the patient smoked, chewed tobacco, or used snuff in the past? What about parenteral drugs (legal or illegal)? Has the patient been overweight?
Does cardiovascular disease start with sudden decompensation?
In many adults, especially the elderly, cardiovascular disease does not start with sudden, significant decompensation. A careful history can reveal past evidence of cardiac problems. The following areas should be reviewed.
When was the first heart attack surgery performed?
The first successful coronary artery bypass graft (CABG) was performed in the 1960's and this surgery was very successful for the next 20 years.
What were the new medications used in the 1970s?
Significant improvements were seen in the 1970's with the use of medications called beta blockers, angiotensin-converting enzyme (ACE) inhibitors and thrombolytic therapy . Beta-blockers help the heart maintain a stable rhythm and protect the heart from having a second heart attack.
What causes a heart attack?
What causes a heart attack? The heart has vessels called coronary arteries. People who are over weight, have high cholesterol, who smoke, have high blood pressure or diabetes have a greater chance of having a buildup of what's called plaque in their coronary arteries. If any of these arteries are blocked, then the heart cannot get blood to that part of the heart, and the person will have a heart attack. Patients having a heart attack will usually primarily complain of chest pain, but there are other symptoms that may not involve chest pain.
How long after heart attack can you have a stress test?
Patients typically have frequent doctor visits to their cardiologist for several months after the heart attack. These visits will include blood pressure and heart rate check, EKG, lab work and some will have an exercise stress test or echocardiogram (ECHO) a few months after their heart attack. The exercise stress test and ECHO will determine how ...
What is an EKG?
Early Diagnostic Tools and Treatments. The electrocardiogram (EKG) is a device used to monitor the heart's rhythm and determine abnormal patterns. The EKG was invented in the early 1900s and helped physicians to determine if someone was having a heart attack. Before this time all they had was a stethoscope.
What is the best medicine for a second heart attack?
Beta-blockers help the heart maintain a stable rhythm and protect the heart from having a second heart attack. Another medication that was introduced during the 1970's is called angiotensin-converting enzyme inhibitors also known as ACE inhibitors.
When was CABG first used?
Animals were used as practice and the first successful human CABG was completed in the early 1960's.
What was the first RCT of antihypertensive therapy?
The Veterans Administration (VA) cooperative study on antihypertensive agents was a major milestone achieved in medicine. This was the first adequately powered placebo-controlled, RCT of antihypertensive therapy ( 15 ). The phase 1 of the study examined active treatment (hydrochlorothiazide, reserpine, and hydralazine) vs. placebo in 143 veterans with severe hypertension (diastolic blood pressure 115–129 mmHg) and achieved an average fall of blood pressure by 43/30 mmHg in the treated group. The recruitment started in 1964 and average follow-up was about 1.5 years. The results of the study showed clear morbidity and mortality benefit, most remarkably in reduction in progression to accelerated/malignant hypertension in the treatment group.
What is the landmark study in African Americans for determining target blood pressure and suitable drug regimen in hypertension control to prevent?
Landmark study in African Americans for determining target blood pressure and suitable drug regimen in hypertension control to prevent progressive renal failure. The study failed to show benefits of tight BP control over usual control to slow decline in GFR.
What is the Tomhs trial?
The TOMHS trial ( 23) was a randomized double-blind placebo controlled trial set up to compare the BP lowering effects of six treatment regimen in patients with stage 1 hypertension (defined as diastolic blood pressure DBP 90–99 mmHg and systolic blood pressure, SBP 140–159 mmHg).
What is the target diastolic pressure?
The Hypertension Optimal Treatment ( 26) (HOT) was a large multicenter trial designed to examine if lowering target diastolic pressure to 85 or 80 mmHg reduces CV events or mortality.

The secondary objectives of the trial were to compare the effectiveness and adverse effects of two antihypertensive drugs bendrofluzide and propranolol.
What is the 18 risk factor intervention?
The Multiple Risk Factor Intervention Trial ( 18) was an ambitious randomized primary prevention trial to test the efficacy of a multifactor intervention program on mortality from coronary heart disease (CHD) in 12,666 high-risk men aged 35–57 years. Men were randomly assigned either to a special intervention (SI) program consisting of stepped-care treatment for hypertension, counseling for cigarette smoking, and dietary advice for lowering blood cholesterol levels, or to their usual sources of health care in the community.
When was the HDFP trial published?
Published in 1979 , the Hypertension Detection and Follow-Up (HDFP) trial was another land mark trial of antihypertensive therapy and was the first study to demonstrate a mortality benefit of goal-directed, stepped care blood pressure treatment compared to usual care ( 17 ).

Perhaps one of the easiest cardiovascular disease treatments involves making sensible changes in your daily routine to slow or reduce symptoms. The NIH includes the following suggestions that you might want to discuss with your doctor:
What is the best treatment for heart disease?
The National Institutes of Health says that most people with heart disease can probably benefit from cardiac rehabilitation (or “rehab”), a medically supervised program to help improve your heart health.
What is the name of the disease that affects the heart?
Cardiovascular disease , also called heart disease, describes a number of conditions that affect your heart, according to the Centers for Disease Control (CDC). These conditions may include atherosclerosis (a build-up of plaque in the arteries), arrhythmia (irregular heart rate), and heart failure.

Cardiac rehab typically involves a personalized exercise program and education about your condition and how to stay as healthy as possible.
What is the procedure called when a tube is inserted through a blood vessel and threaded to the blocked?
Also called angioplasty, this is a nonsurgical procedure in which a thin tube is inserted through a blood vessel and threaded to the blocked artery. A balloon-type structure at the end of the tube is inflated, pressing the plaque against the artery wall and opening the blockage.
Does Medicare cover cardiovascular screening?
Whether you’re enrolled in Original Medicare (Part A and Part B) or in a Medicare Advantage plan, you’re generally covered for most cardiovascular disease treatments and screening tests. Medicare Part A covers treatment you receive as an inpatient in a hospital, while Medicare Part B covers doctor visits, tests, and outpatient procedures. Some restrictions apply; for example, under Original Medicare, treatment must be medically necessary as determined by a Medicare-assigned doctor. If you have a Medicare Advantage plan, your plan might require you to stay within the plan’s provider network.
Is weight a risk factor for heart disease?
Weight is a significant risk factor for heart disease, according to the NIH. Your health-care provider can tell you whether you need to lose weight, and recommend steps you can take toward that goal. For some people, these lifestyle changes may be all the treatment needed to restore heart health.
Why are cardiac patches used?
Additionally, cardiac patches are widely used for the repair of heart injuries caused by myocardial infarctions. However, many times the sutures performed to attach these patches to myocardium may be very harmful to the damaged organ. In this regard, the utilization of nanoscaffolds composed of albumin electrospun fibers and gold nanorods as a platform for the growth and differentiation of cardiac cells allows integrating this hybrid patch to the myocardium by near-infrared laser irradiation without the need of using any sutures [95].
How do cardiovascular diseases affect the world?
Although significant progress has been made in clinical treatment, cardiovascular diseases (CVD) remain a leading cause of death worldwide. Heart-related diseases lead to more deaths than cancer (26.6% versus 22.8%) per year. 1 If stroke is included, CVDs are responsible for almost one-third of all deaths. Meanwhile, CVDs also contribute a major economic burden to our health-care system. Current existing treatments for CVDs are still limited and advanced therapies, especially for myocardial infarction (MI) and atherosclerosis, are scarce. After an acute myocardial infarction, cardiomyocytes cannot be replaced or regenerated to replace the dead cells through stem cell recruitment and the self-renewal rate is far behind the rate of loss of the cardiomyocytes. Non-contractile scar tissue then forms in the area of the infarct. Finally, the myocardium may lose its contractile function, which leads to congestive heart failure. Traditional treatments include the implantation of mechanical valves or biological valves (auto- or allo-grafts). However, the limited number of donors is far behind the number of patients requiring treatment. A promising approach includes the construction of stem cells and cardiac tissue or engineered cardiac tissue. For example, a decade ago, Li et al. seeded fetal rat myocytes on biodegradable gelatin meshes (15 × 15 × 5 mm 3 ). 2 After 1 week of culture, meshes were implanted into the subcutaneous tissue or myocardial scar tissue in a cryoinjured rat heart. Five weeks later, the grafts in the subcutaneous tissue contracted regularly and spontaneously. For grafts in myocardial scar tissue, the cells within the graft survived and formed junctions with the recipient heart cells. The ultimate goal of engineered cardiac tissues (ECTs) is to reconstruct a replica from the damaged cardiac tissues with structural and functional integrity. The graft needs to meet multiple requirements including (1) sufficient elastic (tension and compressive) properties to minimize the risks of arrhythmias or dysfunctions, (2) biocompatibility, and (3) improvement of stem cell regrowth and differentiation.
What is IR in cardiomyocytes?
Myocardial ischemia-reperfusion injury (IR) stimulates ROS production, calcium overload, and quick alterations of myocardial intracellular pH; all these modifications provoke a mitochondrial lesion that consequently leads to cell death (by necrosis or apoptosis) of cardiomyocytes in the initial phase of IR injury. Some recent reports indicate that, in the late phase of injury, monocyte recruitment occurs to the site of the lesion, which produces myocardial inflammation. Endogenous angiotensin II plays a crucial role in this event. Of particular interest, a bioabsorbable formulation based on nanoparticles of PLGA charged with irbesartan, an angiotensin II type 1 receptors antagonist, has been designed. These nanoparticles are intravenously administered at the moment of reperfusion, and they arrive at myocardium injured by ischemia, avoiding monocyte recruitment and decreasing infarct size by anti-inflammatory mechanisms. Reperfusion therapy with nanoparticles charged with irbesartan is a new approach for myocardial IR injury treatment in patients with AMI [85]. It has also been demonstrated that adenosine produces a robust cardioprotective effect when it is administered at the beginning of cardiac reperfusion. Nevertheless, the clinical utilization of adenosine for myocardial protection is restricted because of its adverse effects, such as bradycardia and hypotension. To overcome this limitation, a formulation based on silica nanoparticles oriented to facilitate myocardial drug delivery has been designed. Functionalization of the silica nanoparticles surface with adenosine produces a further limitation of infarct size in animals. Also, the hypotensive side effect of adenosine was reduced after its adsorption on silica nanoparticle's surface [86]. Lipid nanocarriers loaded with oleate adenosine prodrug and modified with atrial natriuretic peptide-di-stearoyl phosphatidylethanolamine-polyethylene glycol have also been developed for the treatment of myocardial infarction by intravenous administration with promising results [87].
What is cardioprotective diet?
A cardioprotective diet is an important lifestyle practice that is the cornerstone of CVD risk management ( Mozaffarian et al., 2011 ). The purpose of this article is to review the current evidence in support of contemporary dietary recommendations for CVD prevention and treatment.
Why are heart lesions permanent?
Heart lesions are usually permanent due to the limited capacity of proliferation and self-repair of cardiomyocytes. Hence, therapies with stem cells have become attractive alternatives in cardiovascular disease treatment [80]. Nevertheless, despite endeavors to optimize this therapy, issues related to delivery and tracing or monitoring of injected cells into the myocardium still exist. Moreover, there are difficulties in enhancing the survival of transplanted stem cells, such as the insufficiency of suitable techniques for their viability evaluation. Furthermore, less than 10% of the transplanted stem cells stay at the target site a few hours after injection. To overcome these limitations, new procedures are needed to reach a high concentration of cells in the damaged tissue and monitor their viability and proliferation. Magnetic resonance has become a dependable and secure technique for tracking stem cells. Nonetheless, the sensitivity and success of this technique mostly depend on the kind of contrast agent used. In this sense, because of their distinctive magnetic properties and high biocompatibility, iron oxide superparamagnetic nanoparticles can be utilized for the targeting and monitoring of stem cells in AMI treatment. Iron oxide superparamagnetic nanoparticles are known as one of the most useful contrast agents commercially available for the labeling of stem cells [81, 82].
What is the role of epigenetics in cardiovascular disease?
Accumulating evidence suggests that epigenetic regulation including DNA methylation, histone modification, and microRNA alteration may play an important role in cardiovascular disease. As a postmitotic cell, cardiac myocytes must rely on comprehensive protein quality control mechanisms to maintain cellular function and homeostasis. Autophagy, an evolutionarily conserved catabolic pathway responsible for degradation of long-lived proteins and defective organelles, is one such quality control mechanism and has been proposed as a therapeutic target for cardiovascular disease. Recent studies have demonstrated that alteration of epigenetic pathways can modify autophagic activity and impact cardiac function and cardiac myocyte survival. Here, we summarize the current knowledge regarding the functions of autophagy and epigenetics in cardiovascular disease.
Is cardiovascular disease preventable?
1 Nevertheless, 70% of cardiovascular disease is preventable through lifestyle changes alone. 2 Clearly, we have work to do.
