While at the same it has been creating many complexities which create catastrophic concerns for the wellbeing of the mankind. With meticulous attention and carefulness, we can solve the indomitable medical problems, but at the same time, minor negligence or lack of awareness can cause the reverse effect and can be proved fatal.

Cardio Vascular Disease, Treating Heart Diseases

Modern science and technology has been helping the humanity by proving comfort and convenience; easing efforts and efficacies; creating hopes and happiness; and resolving concerns and catastrophes. The inventions, innovations and revolutions in modern healthcare industry are boons of the modern science and technology. This has been creating hopes in the mostly affected, afflicted and disease stricken humanity. In the advent of the modern medical science, the irredeemable and unconquerable diseases, epidemics and chronic illness have been defeated severely.

As the world is grappling with human plight, unhappiness and illness due to various disease and ailments, we can never neglect heart diseases which can creates catastrophic concerns for most wealthy and developing nations. We have been observing the struggles of humanity to cope up with the seriousness of the cardio vascular diseases and its complexities. According to Neo Crdia Care, one fifth of the deaths in India are from coronary heart disease. By the year 2020, it will account for one third of all deaths.. Heart disease in India occurs 10 to 15 years earlier than in the west.

Premature mortality in terms of years of life lost because of CVD in India increased by 59%, from 23.2 million (1990) to 37 million (2010).


17.5 million

people die each year from CVDs, an estimated 31% of all deaths worldwide


of CVD deaths occur in low-income and middle-income countries


of all CVD deaths are due to heart attacks and strokes.

Modern technology for cardio vascular disease: boons and bans for the heart patients:

Cardio vascular disease has been creating a catastrophic concern for the human society. Irrespective of the livelihood people the deadly disease creating alarming concerns for the humanity. Of the 30 million heart patients in India, 14 million reside in urban areas and 16 million in rural areas. In the current scenario, cardiac hospitals in India perform highest, open heart surgeries per year worldwide which is more than 2, 00,000. Hence, cardiologists and scientist have been trying their best discover more innovative and realistic medical technologies for the various cardio vascular diseases.

The tools are becoming boon for the human society and come with many innovative technologies. Though the tools provide great relief and solutions to the incurable problems, these are not appropriate cure for the required disease. Hence these come with many limitations in it.


Various medical technologies for CVDs: an analysis of their pros and cones

Modern healthcare technology has been drastically developing newer and advanced diagnosis, medication, treatment and care for the deadly cardio vascular diseases. As people are getting benefitted from the newer heart technologies, these are also associated with some disadvantages that are considered to be the drawbacks of the inventions. If not properly manages and controlled these technologies will be converted into bans for these treatments.

Pros and cons of external Defibrillator (ICD)

Defibrillation is a procedure used to treat life threatening conditions that affect the rhythm of the heart such as cardiac arrhythmia, ventricular fibrillation and pulseless ventricular tachycardia. It delivers a therapeutic dose of electric shock or countershock to the heart through device called defibrillator. This electrical shock is given to reset the electrical state of the heart so that it may beat to a rhythm controlled by its own natural pacemaker cells.

Advantages and disadvantages of manual external defibrillator

Manual external defibrillators (MED) are devices with electrocardiogram (EKG) displays are used to diagnose the rhythm of the heart without any automatic function. All the MEDs predominantly have three basic modes of operational function such as synchronized cardioversion, external defibrillation, and internal defibrillation. Some advanced defibrillators are integrated into machines that monitor oxygen levels in the blood, concentration of exhaled carbon dioxide at the end of a breath, and blood pressure.

Easy and user friendly manual operation of the defibrillator without any integrated computer calculation helps the doctors or the nurses can operate the device without any risk of computer malfunction.

However, less skilled and less experienced doctors’ and nurses’ decision determine the amount of the shocks for the patient which might not accurate every time. In this condition, too less and or too more shocks can determines the recovery of the patients’ natural pacemakers. A computer system could be helpful in this regard to determine the exact amount of shock needed to be given to the patient.

Advantages and disadvantages of automated external defibrillator

An automated external defibrillator (AED) is a portable defibrillator that automates the heart rhythm problem by providing an electric shock to the heart to try to restore a normal rhythm. AEDs are best benefitted and used to treat suddenly and unexpectedly stop of hart beat and cardiac arrest.

Advantages of using an AED include the ease and safety of the using the devices for a faster and better delivery of the electrical shock. The automatic analysis of the current condition of the heart rhythm makes it easy to decide and provide the required amount of electric shock. Unlike other defibrillator, very less training is required for the operating AED.

As far as the disadvantages are concerned, the only possible risk would be starting a fire due to the electrical current. In emergency situation, AEDs cannot be used at home as it required professionals to use and provide the electric shock. Some AEDs lack delivering pulses of current to stimulate heart contraction and converting tachycardia or arrhythmia to a normal heartbeat.

Pros and cons of Implantable Cardioverter Defibrillator (ICD)

Unlike AED and MED, an Implantable Cardioverter Defibrillator (ICD) is a battery-powered defibrillator device planted under the chest or abdomen to keep track of the heart rate and control the irregular heart beat called arrhythmias . With help of thin wires ICD is connected to the heart. In case of an abnormal or irregular heart rhythm, the device delivers an electric shock to restore a normal heartbeat and creates condition of so that heart beats normally to its natural pacemaker.


Cardio Vascular Disease, Pacemaker, Treating Heart diseases


All the ICDs contain two leads to insert into upper and lower chamber of heart. Ideally these two leads are placed in two veins under the upper chest under the clavicle by making a small opening at the upper chest and inserting two leads of the ICD into the veins. Usually, two leads are inserted, one into the right lower chamber, and the other into the right upper chamber. The leads are actually attached to the heart muscle via a tiny screw at the tip of the lead.

With the creation of magnetic field within, it make a person incompatible with MRIs. People with professional who include interacting machineries of large magnetic field must strictly avoid using these.

With the advent of foreign object inside the body, chances of the infection and associated complication are unavoidable. Identifying and treating these infections are difficult tasks as these happen inside the body. To treating these infections the devices need to be removed and replaced which associated with complexities.

Pros and cons of Bioresorbable Stents

Cardio Vascular Disease, Treating Heart Diseases

Scaffolds or stents are specially designed tubes which are interested in the narrowed down arteries to support the artery wall and releasing drugs to keep blood vessel wall open. Eventually, clots can form inside the stents and creates other issues. Keeping the issue in t mind, the Bioabsorbable scaffolds are used. Bioabsorbable scaffolds also stents made up of special materials which can get dissolved after the required job is done. They ideally break down and decompose after their work is done.

They help treated blood vessels to regain their ability to constrict and expand. The recent use of the everolimus-eluting bioresorbable stent effectively used like other commonly used drug-eluting stents.


The Bioresorbable Stents helps:

  • Solving the restenosis problems
  • Avoiding the clot formation problem
  • Avoiding anti-clotting medication need
  • Avoiding chronic, inflammatory processes

Recently available bioresorbable stents are harder to place inside arteries than metal stents earlier available since these harder and less flexible. This is becoming a limitation of using this in more complex coronary artery disease. Controlling the degree of the desolation and the size of the degradation products. Based on the blood flow pressure certain portion of stent may not be harmoniously degraded. For example if the middle of the stent degrades first, a large portion of the stent may break off and float downstream raising embolism concerns.

Pros and cons of Pacemakers

Cardio Vascular Disease, Treating Heart Diseases

Pacemakers small driven by low-energy electrical pulses often installed in the chest or abdomen to help control abnormal heart rhythms. It is extremely beneficial for those whose heart rates are extremely slow and irregular. It helps restore the heart rate and enable placed in the chest or abdomen to help control abnormal heart rhythms by adding an electrical impulse to the heart muscle when necessary. After this is successfully installed, it eliminates the symptoms of bradycardia, relieving shortness of breath and chronic fatigue.

The benefits are immediate after the installation of the pacemaker for the people suffering from bradycardia. Based on the condition of the heart, the pacemaker can be programed and installed in the top or bottom chamber as well as right and left ventricles. This provides long lasting solution to the without maintenance.

How eve pacemaker has some draw backs. As it uses magnetic and electromagnetic energy, it creates magnetic field. Those who are working under magnetic fields they strictly have to avoid this. Even an accidental failure to avoid appliances and devices that has magnetic field that interfere with the pacemaker could have dire consequences .As a foreign object it being installed inside the body, there are chances of the infection in around the pacemaker and can spread to other places of the body. The infection spreads there might need of the removal of the pacemaker which can be life threatening. In rare cases, if it does not work properly it has to be replaced through surgery which is also risky. Moreover this in not a cure rather it temporary treatment which may not prevent heart attack and improves cardio vascular functioning.
